Novel highly efficient fluoroionophores with a peri-effect and strong electron-donating receptors: TICT-promoted PET and signaling response to transition metal cations with low background emission

Novel fluoroionophores with piperazine frameworks as receptors for transition metal cations have been designed with the aid of calculation and synthesized. They exhibited low background emission and highly efficient fluorescence enhancements upon complexation with different transition metal cations, which could be ascribed to the special contribution of the TICT-promoted PET processes caused by the peri-effect and strong electron-donating receptors.

Structure-property relationships in conjugated donor-acceptor systems functionalized with tetrathiafulvalene

The properties of two donor-acceptor compounds tetrathiafulvalene- acenaphtho[1,2-b] quinoxaline (1) and tetrathiafulvalene-3-nitro-acenaphtho[1,2- b]quinoxaline (2) have been investigated by solution-state studies (electrochemistry, absorption, self-assembly) and theoretical calculations (DFT, TD-DFT). The electrochemical studies indicate the nitro-substituted effect on their redox properties is negligible. Both compounds show effective intramolecular charge transfer (ICT) transitions in the UV-Visible range in solution. Compared with compound 1, compound 2 has a bathochromic shift in the absorption spectra, the λmax-ICT has been extended from 20800 cm-1 to 19700 cm-1 (480 nm to 507 nm). In addition, when the nitro group is employed, the self-assembly characteristics of the two compounds are substantially changed from ribbon-like nanostructures to root-like nanostructures. Density functional theory (DFT) calculations provide insights into their molecular geometries, electronic structures, and physico-chemical properties.

Preparation of chiral trans-5-substituted-acenaphthene-1,2-diols by baker's yeast-mediated reduction of 5-substituted-acenaphthylene-1,2-diones

A series of trans-5-substituted-acenaphthene-1,2-diols were obtained in 21-72% yield with 97-100% ee by baker's yeast-mediated reduction of the corresponding acenaphthylene-1,2-diones, in the presence of DMSO as a co-solvent and under vigorous agitation.
