a nitric oxide induced click reaction to trigger the aggregation induced emission aie phenomena of a tetraphenyl Ethylene Derivative a new fluorescent probe for no
Journal of Photochemistry and Photobiology A-chemistry, 2020Co-Authors: Silvia Rodrigueznuevalos, Margarita Parra, Samuel Ceballos, Salvador Gil, Ana M CosteroAbstract:Abstract An Aggregation Induced Emission (AIE) transduction mechanism has been used to detect nitric oxide (NO). A new tetraphenylEthylene Derivative functionalized with alkyne moieties has been prepared to work as a fluorescent probe. A “click” reaction was chosen because NO is able to generate the required catalytic species by reducing Cu(II) to Cu(I).

Synthesis and Structural Characterization of Pincer Pyridine Diphosphite Complexes of Rhodium and Iridium
European Journal of Inorganic Chemistry, 2011Co-Authors: Miguel Rubio, Andrés Suárez, Esmeralda Vega, Eleuterio Álvarez, Josefina Díez, M. Pilar Gamasa, Antonio PizzanoAbstract:The synthesis of a novel pyridine diphosphite ligand 1 has been described. From this ligand, rhodium– and iridium–chlorido complexes of formula [MCl(1)] (M = Rh, Ir) have been prepared. Chloride abstraction by treatment with NaBPh4 and a phosphane produced the corresponding cationic phosphane Derivatives [M(1)L][BPh4] [L = PPh3 (Rh, Ir), PPh2Me (Ir)]. The analogous reaction of [RhCl(1)] with CNXy (Xy = 2,6-Me2-C6H3) and NaBPh4 yielded the monosubstituted complex [Rh(1)(CNXy)][BPh4], whereas the reaction between [IrCl(1)] and isonitriles led to the disubstituted complexes [Ir(1)(L)2][BPh4] (L = CNBn, CNCy). Ethylene compound [Rh(1)(C2H4)][BPh4] was obtained from the reaction of [RhCl(1)] with NaBPh4 under Ethylene, whereas [Ir(1)(C2H4)][BPh4] was synthesized by a treatment of [{IrCl(COE)2}2] with Ethylene followed by addition of 1 and NaBPh4. An IR analysis of the isocyanide complexes indicates a very poor π-donor ability of the [M(1)]+ fragment, therefore the isocyanide metal bond is mostly due to σ donation from the isocyanide. Characterization by X-ray crystallography of [Rh(1)(PPh3)][BPh4], [Rh(1)(MeCN)][BPh4] and [Ir(1)(PPh2Me)][BPh4] displays a square-planar structure with ligand 1 coordinated in a pincer fashion for these complexes. In addition, the Ethylene Derivative [Rh(1)(C2H4)][BPh4] shows a near in-plane conformation of the Ethylene ligand, with a short C–C distance (1.319 A). Moreover, in all the structures, the diphosphite ligand exhibits a meso conformation irrespective of the size of the neutral ancillary ligand. An examination of the behaviour of some of these complexes in catalytic hydrogenation has shown that [IrCl(1)] is an active catalyst in the reduction of 2-methylquinoline and 2-methylquinoxaline.

The synthesis and fluorescence of a new biphenyl Ethylene Derivative sensitive to DNA induced by single- and two-photon excitation
Synthetic Metals, 2013Co-Authors: Jing-jing Zhang, Xian Zhang, Xiang-long Meng, Jinshui Yao, Weiliang Liu, Ying-kai LiuAbstract:Abstract A new biphenyl Ethylene Derivative, 4,4′-bis-(2-(4-N-ethyl-N-ethoxyl-amino) styryl] biphenyl (BEEASP) was successfully synthesized and studied as a potential fluorescent probe of DNA detection. The linear absorption and fluorescent spectra of the dye in different solvents were investigated. The absorption, one- and two-photon fluorescent spectra of the free dye and dye–DNA complex were also examined to evaluate their photophysical properties. The binding constant of dye–DNA was calculated with a moderate value. Two-photon active cross-sections (Фδ) were finished by the reference method, and the value at a stable complex of dye–DNA was about 37 GM. The experimental results showed that BEEASP can be used as an efficient fluorescent probe to detect DNA by single-photon excitation and two-photon excitation. The fluorescent method date indicated that the mechanism of dye–DNA complex interaction may be the groove binding.
