The optical and redox properties of a methyl pyridinium appended 1,2-dithienylethene photochromic derivative have been thoroughly investigated. A complex multi-step photo/redox mechanism is proposed for the closed isomer on the ground of spectro-electrochemical and theoretical data. The generated compounds are not stable over the time because of chemical reactions associated to the redox processes and a new dithienylethene derivative incorporating a seven-membered ring has been isolated and characterized.
研究了一种甲基金属吡啶鎓取代的 1,2-二噻烯光致变色衍生物的光学和氧化还原性质。根据光谱电化学和理论数据，提出了一个复杂的多步光/氧化还原机理，用于闭合异构体。由于与氧化还原过程相关的化学反应，生成的化合物在时间上不稳定，并且已经分离和表征了一种新的包含七元环的二噻烯衍生物。
