, p. 6552 - 6556 (2010)
Two molecular tweezers containing a tetrathiafulvalene vinylogue (TTFV) core were synthesized via sequential Sonogashira and Horner-Wadsworth-Emmons (HWE) reactions. The electrochemical and spectroscopic properties of these TTFV tweezers were investigated by UV-vis absorption spectroscopy, cyclic voltammetry, and spectro-electrochemical measurements. The property characterizations suggest potential application in electrochemically-actuated molecular switching devices.

Tweezer-like molecular systems containing a redox-active tetrathiafulvalene vinylogue (TTFV) unit and two phenylboronate or phenylboronic acid endgroups were synthesized via the Cu-catalyzed alkyne azide coupling (i.e., click) reaction. The TTFV-phenylboronic acid derivative was found to show different differential pulse voltammetric (DPV) responses to various monosaccharides in aqueous DMSO at pH 7.41, suggesting potential use in electrochemical sensing of saccharides. Moreover, the TTFV-phenylboronate derivative exhibited strong binding to the fluoride ion, giving rise to sensitive electrochemical detection of the fluoride ion.

Tetrathiafulvalene vinylogue (TTFV) was functionalized with two anthryl fluorophores via Cu(i)-catalyzed alkyne-azide [3 + 2] cycloaddition, forming a dianthryl-TTFV hybrid to show fluorescent turn-on sensing behaviour for Cu 2+, Fe2+, and Cd2+ ions in THF with remarkably low detection limit down to the sub-ppm level.

(Chemical Equation Presented) An acetylenlc phenyldlthlafulvene was developed as a versatile synthon for diverse TTFV-based macromolecular scaffolds. Through different coupling reaction sequences, shape-persistent macrocycles and linear TTFV-embedded polymers have been obtained and thereafter characterized by spectroscopic and voltammetrlc analyses. The TTFV polymer thin films generated via electropolymerlzatlon of a dlthlafulvenyl-end-capped dlyne monomer showed promising prospects In electrochromlc and redox swltchable molecular devices.
