  • Solid-state polymerisation via [2+2] cycloaddition reaction involving Coordination Polymers
    Chemical Communications, 2016
    Co-Authors: Raghavender Medishetty, In Hyeok Park, Shim Sung Lee, Jagadese J. Vittal
    Abstract:

    Highly crystalline metal ions containing organic Polymers are potentially useful to manipulate the magnetic and optical properties to make advanced multifunctional materials. However, it is challenging to synthesise monocrystalline metal complexes of organic Polymers and single-phase hybrid materials made up of both Coordination and organic Polymers by traditional solution crystallisation. This requires an entirely different approach in the solid-state by thermal or photo polymerisation of the ligands. Among the photochemical methods available, [2+2] cycloaddition reaction has been recently employed to generate cyclobutane based Coordination Polymers from the metal complexes. Cyclobutane Polymers have also been integrated into Coordination Polymers in this way. Recent advancements in the construction of polymeric chains of cyclobutane rings through photo-dimerisation reaction in the monocrystalline solids containing metal complexes, Coordination Polymers and metal-organic framework structures are discussed here.

  • solid state reactivity and structural transformations involving Coordination Polymers
    Chemical Society Reviews, 2013
    Co-Authors: Goutam Kumar Kole, Jagadese J. Vittal
    Abstract:

    This tutorial review discusses recent literature on Coordination Polymers and metal–organic frameworks (MOFs) that exhibit solid-state reactivity and structural transformation under various experimental conditions. Removal or exchange of solvents and guest molecules, exposure to reactive vapours, and external stimuli such as heat, light or mechanochemical force cause such structural transformations and these are often manifested by various physical properties such as colour, magnetism, luminescence, chirality, porosity, etc. due to change in Coordination number and geometry, dimensionality, interpenetration, etc. More drastic transformations related to the exchange of metal ions, pillar ligands and insertion of additional ligands between the layers have also been demonstrated. The vast area of dynamic behaviour of Coordination Polymers and their stimuli-responsive properties have also been addressed briefly.

  • supramolecular structural transformations involving Coordination Polymers in the solid state
    Coordination Chemistry Reviews, 2007
    Co-Authors: Jagadese J. Vittal
    Abstract:

    Structural changes are accompanied by the movements of atoms/molecules and hence transformation of one structure to another is difficult in the solid state due to the restricted movements of molecules. While single-crystal to single-crystal conversion is more convenient way of characterizing the structures in the solid state by X-ray crystallography, the single crystalline nature of Coordination Polymers may not be always retained during structural transformations, since breaking and forming of coordinate and/or covalent bonds occur in more than one direction. X-ray powder diffraction techniques, thermoanalytical methods, solid-state NMR spectroscopy may be used to extract structural information in the topochemical reactions. This review describes a personal account of the structural transformations involving Coordination Polymers in the solid state along with other relevant and interesting examples from the literature.

  • Coordination Polymers of d10 metals and n n bis 3 pyridinecarboxamide 1 2 ethane
    Journal of The Chemical Society-dalton Transactions, 2001
    Co-Authors: Sebastian Muthu, Jagadese J. Vittal
    Abstract:

    The ligands N,N′-bis(3-pyridinecarboxamide)-1,2-ethane (L) was designed to form Coordination Polymers capable of assembling into 2-D network via complementary amide hydrogen bonds. The reactions of L with AgX (X = ClO4−, CF3SO3− or NO3−), Zn(ClO4)2·6H2O and Cd(ClO4)2·6H2O produced Coordination Polymers 1–5,the structures of which were characterized by single crystal X-ray diffraction. The polymer {[AgL][ClO4]}∞ crystallized in two polymorphs 1A and 1B which consisted of Coordination Polymers {[AgL]+}∞ in sine-wave and zigzag conformations, respectively. In addition, the X-ray crystal structures of {[AgL][CF3SO3]}∞ (2) and {[AgL][NO3](H2O)1.25}∞ (3) showed Coordination Polymers in zigzag conformation similar to that of 1B. The Polymers in compounds 1, 2 and 3 aggregate via complementary amide hydrogen bonds, forming corrugated sheets in the solid state. Furthermore, the compound trans-{[ZnL2(H2O)2][ClO4]2·(H2O)2·CH3CN}∞ (4) was shown to be an infinite chain of [Zn2L2] metallacycles. The stacking of the Zn polymer leads to the formation of a channel-like structure. The Coordination polymer {[CdL(H2O)3][ClO4]2}∞ (5) shows zigzag chains which are linked through hydrogen bonds between the anion, amide groups and coordinated water molecules. In contrast to its isomer L, the ligand N,N′-bis(2-pyridinecarboxamide)-1,2-ethane (L1) formed segregated Ag(I) Coordination polymer (6) in which the Ag ion is four coordinate.

  • inorganic nanoparticles in porous Coordination Polymers
    Chemical Society Reviews, 2016
    Co-Authors: Takashi Uemura, Susumu Kitagawa
    Abstract:

    Porous Coordination Polymers (PCPs) have been recently highlighted because of their high synthetic designability in structure and functions. Because of their ordered nanoporous structures with a large surface area and tunable pore surface functionality, PCPs have emerged as a significant class of nanoporous materials with potential applications in gas storage, separation, catalysis, and chemical sensing. Recent research has shown the utility of PCPs as host materials for the confinement of nanoparticles of inorganic Polymers (IPs), such as metals, metal oxides, and metal chalcogenides. The fabrication of IP nanoparticles in PCPs (PCP⊃IP) has been studied for manifesting specific nanosized-dependent properties and host–guest synergistic functions. In this review, we describe the recent progress in the accommodation of IPs in the nanochannels of PCPs and the remarkable functions of the composite materials.

  • functional hybrid porous Coordination Polymers
    Chemistry of Materials, 2014
    Co-Authors: Ryotaro Matsuda, Susumu Kitagawa
    Abstract:

    Porous Coordination Polymers (PCPs) have attracted vast interest in recent years because of their possibility for rational design of crystal structures and functional properties. An emerging trend in PCP research is hybridization, which is the subject of this review. We have divided hybrid PCPs into three broad classes: class I, isomorphous mixed metal/ligand PCPs; class II, core@shell PCPs; class III, PCP⊃guest or PCPs with accommodated guests. In this Review, we examine 62 representative hybrid PCPs in the area of gas adsorption/separation/storage, luminescence, catalysis, drug delivery, and ionic conductivity with representative examples of each class to understand the underlying principles of hybridization for PCPs and their advantages over conventional PCPs. The future directions and applications of hybrid PCPs are postulated.

  • terminology of metal organic frameworks and Coordination Polymers iupac recommendations 2013
    Pure and Applied Chemistry, 2013
    Co-Authors: Stuart R Batten, Neil R. Champness, Lars Ohrstrom, Xiao-ming Chen, Susumu Kitagawa, Javier Garciamartinez, Michael Okeeffe, Jan Reedijk
    Abstract:

    A set of terms, definitions, and recommendations is provided for use in the classi- fication of Coordination Polymers, networks, and metal-organic frameworks (MOFs). A hier- archical terminology is recommended in which the most general term is Coordination poly- mer. Coordination networks are a subset of Coordination Polymers and MOFs a further subset of Coordination networks. One of the criteria an MOF needs to fulfill is that it contains poten- tial voids, but no physical measurements of porosity or other properties are demanded per se. The use of topology and topology descriptors to enhance the description of crystal structures of MOFs and 3D-Coordination Polymers is furthermore strongly recommended.

  • ion conductivity and transport by porous Coordination Polymers and metal organic frameworks
    Accounts of Chemical Research, 2013
    Co-Authors: Satoshi Horike, Daiki Umeyama, Susumu Kitagawa
    Abstract:

    Ion conduction and transport in solids are both interesting and useful and are found in widely distinct materials, from those in battery-related technologies to those in biological systems. Scientists have approached the synthesis of ion-conductive compounds in a variety of ways, in the areas of organic and inorganic chemistry. Recently, based on their ion-conducting behavior, porous Coordination Polymers (PCPs) and metal–organic frameworks (MOFs) have been recognized for their easy design and the dynamic behavior of the ionic components in the structures. These PCP/MOFs consist of metal ions (or clusters) and organic ligands structured via Coordination bonds. They could have highly concentrated mobile ions with dynamic behavior, and their characteristics have inspired the design of a new class of ion conductors and transporters.In this Account, we describe the state-of-the-art of studies of ion conductivity by PCP/MOFs and nonporous Coordination Polymers (CPs) and offer future perspectives. PCP/MOF struc...

    Co-Authors: Julien Reboul, Shuhei Furukawa, Nao Horike, Manuel Tsotsalas, Kenji Hirai, Hiromitsu Uehara, Mio Kondo, Nicolas Louvain, Osami Sakata, Susumu Kitagawa
    Abstract:

    The spatial organization of porous Coordination-polymer crystals into higher-order structures is critical for their integration in heterogeneous catalysts, separation systems and electrochemical devices. A method for spatially controlling the nucleation site leading to the formation of mesoscopic architecture in porous Coordination Polymers, in both two and three dimensions, is now demonstrated.

  • single crystal x ray diffraction studies on structural transformations of porous Coordination Polymers
    Chemical Society Reviews, 2014
    Co-Authors: Jiepeng Zhang, Peiqin Liao, Haolong Zhou, Xiao-ming Chen
    Abstract:

    X-Ray single-crystal diffraction has been the most straightforward and important technique in structural determination of crystalline materials for understanding their structure–property relationships. This powerful tool can be used to directly visualize the precise and detailed structural information of porous Coordination Polymers or metal–organic frameworks at different states, which are unique for their flexible host frameworks compared with conventional adsorbents. With a series of selected recent examples, this review gives a brief overview of single-crystal X-ray diffraction studies and single-crystal to single-crystal transformations of porous Coordination Polymers under various chemical and physical stimuli such as solvent and gas sorption/desorption/exchange, chemical reaction and temperature change.

  • supramolecular isomerism in Coordination Polymers
    Chemical Society Reviews, 2009
    Co-Authors: Jiepeng Zhang, Xiaochun Huang, Xiao-ming Chen
    Abstract:

    Coordination Polymers have been emerging as a topical research field in crystal engineering, solid-state chemistry, and materials science. Considering the wide occurrence of structural and compositional diversity during self-assembly and crystallization, supramolecular isomerism represents an indication of composition control and structure prediction. Actually, supramolecular isomerism is not just an obstacle or challenge, but also a good opportunity for developing novel materials and a better understanding of self-assembly and crystal growth. This critical review provides an overview of the developing knowledge, in the context of supramolecular isomerism, of the design, synthesis, and properties of Coordination Polymers (97 references).
