Photoelectrochromic Organic Systems

Resumo

The electrochemical properties of photochromic compounds from the classes of diarylethenes, fulgides, quinones, spiropyrans, and dihydropyrenes exhibiting photoelectrochromic properties were analyzed for the first time. It was demonstrated that, depending on the structure and on the nature of the substituents, these compounds can exhibit electrochromic transformations under reversible oxidation of both the initial and photoinduced forms. Photochromic and electrochromic properties displayed by a number of organic compounds make them promising candidates for development of new dual-mode photo- and electrocontrolled switches for various applications.
