Electrocatalytic oxidative Z/E isomerization of a stilbene favoured by the presence of an electroactive persistent radical

The π-conjugation of an electroactive perchlorotriphenylmethyl (PTM˙) radical to an E/Z switchable stilbene derivative permits to demonstrate that its electrocatalytic Z → E isomerization is undoubtedly triggered by the open-shell nature of PTM˙ unit.

Enhanced E/Z-photoisomerization and luminescence of stilbene derivative co-coordinated in di-β-diketonate lanthanide complexes

Five lanthanide complexes with a stilbene derivative and di-β-diketonates were synthesized and their enhanced E/Z-photoisomerization and luminescence properties were studied.

Stilbene derivative as a photosensitive compound to control the excitability of neonatal rat cardiomyocytes

Substances that can be used as photosensitizers for cardiac tissue are very helpful in modeling various excitation patterns in a cardiac tissue culture and may have prospective use in the temporary and permanent ablation of unwanted excitation sources in the heart. The aim of the present work is to study the effect of stilbene derivative c-TAB (2- {4- [(E) -2- (4-ethoxyphenyl) vinyl] phenoxy} ethyl) trimethylammonium bromide) on the cardiomyocyte layers and voltage-gated ion channels in cardiac cells. C-TAB is a structural analog to AzoTAB, reported previously as a photoswitch for cardiac and neural cells, in which the azobenzene moiety is replaced by a stilbene grouping. Such a replacement makes c-TAB less toxic to living cells. c-TAB has been shown to successfully inhibit excitation in cardiac cells in both trans- and cis- forms. The excitation inhibition of cardiac cells under c-TAB is reversible and can be overturned easily by washing out the c-TAB; however, not by light illumination. The irradiation of cardiac cells with near-UV, when the trans- form of c-TAB is applied, changes reversible inhibition to a permanent one that cannot be overturned by a washout.
