Molecular Engineering of face on oriented dopant free hole transporting material for perovskite solar cells with 19 pce
Journal of Materials Chemistry, 2017Co-Authors: Kasparas Rakstys, Sanghyun Paek, Paul Gratia, Tomasz Marszalek, Giulia Grancini, K Genevicius, Vygintas Jankauskas, Wojciech Pisula, Mohammad Khaja NazeeruddinAbstract:Through judicious Molecular Engineering, novel dopant-free star-shaped D–π–A type hole transporting materials coded KR355, KR321, and KR353 were systematically designed, synthesized and characterized. KR321 has been revealed to form a particular face-on organization on perovskite films favoring vertical charge carrier transport and for the first time, we show that this particular Molecular stacking feature resulted in a power conversion efficiency over 19% in combination with mixed-perovskite (FAPbI3)0.85(MAPbBr3)0.15. The obtained 19% efficiency using a pristine hole transporting layer without any chemical additives or doping is the highest, establishing that the Molecular Engineering of a planar donor core, π-spacer and periphery acceptor leads to high mobility, and the design provides useful insight into the synthesis of next-generation HTMs for perovskite solar cells and optoelectronic applications.

Molecular Engineering of Functional Materials for Energy and Opto-Electronic Applications.
Chimia, 2015Co-Authors: Konrad Domanski, Sadig Aghazada, Kasparas Rakstys, Sanghyun Paek, Mohammad Khaja NazeeruddinAbstract:This review presents an overview of the dedicated research directions of the Group for Molecular Engineering of Functional Materials (GMF). This includes Molecular Engineering aspects of sensitizers constructed from ruthenium complexes, organic molecules, porphyrins and phthalocyanines. Manipulation of organometal trihalide perovskites, and charge transporting materials for high performance perovskite solar cells and photo-detectors are also described. Controlling phosphorescence color, and quantum yields in iridium complexes by tailoring ligands for organic light emitting diodes are demonstrated. Efficient reduction of CO2 to CO using Molecular catalyst on a protected Cu2O photocathode, and cost-effective water-splitting cell using a high efficiency perovskite solar cell are presented.

Molecular Engineering of organic electroactive materials for redox flow batteries
Chemical Society Reviews, 2018Co-Authors: Yu Ding, Changkun Zhang, Leyuan Zhang, Yangen Zhou, Guihua YuAbstract:With high scalability and independent control over energy and power, redox flow batteries (RFBs) stand out as an important large-scale energy storage system. However, the widespread application of conventional RFBs is limited by the uncompetitive performance, as well as the high cost and environmental concerns associated with the use of metal-based redox species. In consideration of advantageous features such as potentially low cost, vast Molecular diversity, and highly tailorable properties, organic and organometallic molecules emerge as promising alternative electroactive species for building sustainable RFBs. This review presents a systematic Molecular Engineering scheme for designing these novel redox species. We provide detailed synthetic strategies for modifying the organic and organometallic redox species in terms of solubility, redox potential, and Molecular size. Recent advances are then introduced covering the reaction mechanisms, specific functionalization methods, and electrochemical performances of redox species classified by their Molecular structures. Finally, we conclude with an analysis of the current challenges and perspectives on future directions in this emerging research field.

Functionalization of carbon nanomaterials by evolutionary Molecular Engineering: Potential application in drug delivery systems
Journal of Drug Targeting, 2006Co-Authors: Kiyotaka ShibaAbstract:By virtue of the progress made in evolutionary Molecular Engineering, peptide aptamers that specifically recognize target molecules are now routinely created using a peptide phage display system. The system was originally developed for isolating peptides that specifically recognized biomacromolecules (e.g. proteinous receptors), but are now also being used to acquire peptide motifs that bind to inorganic materials, such as semiconductors, metals and carbon nanomaterials. We have created the peptide aptamer against carbon nanohorns, a vesicular carbon nanomaterial whose size is 80-100 nm in diameter. By combining the peptide motif that has affinity to the surfaces of carbon nanohorns with peptide aptamers that can target specific organs, we can functionalize the carbon nanomaterial to provide novel types of carriers for drug delivery systems.
