A series of dithienylethene‐containing triarylboranes has been designed, synthesized, and characterized. The electrochemistry, photophysics, and photochromic behavior have also been studied. The photophysical and photochromic properties could be facilely tuned in this system by varying the thiophene spacers (thiophene, thienothiophene, and bithiophene) between the dithienylethene and the dimesitylboron
已设计,合成和表征了一系列含二噻吩基乙烯的三芳基硼烷。还研究了电化学,光物理和光致变色行为。可以通过在二噻吩乙烯和二烯基异丁酮(BMes 2)之间改变噻吩间隔基(噻吩,噻吩并噻吩和联噻吩)或噻吩间隔基中BMes 2取代的位置来方便地调节光物理性质和光致变色性质。已经发现,在引入BMes 2单元后,封闭形式的吸收对结构修饰更敏感。而且,在添加路易斯碱的(获得的多寻址光致变色反应˚F -),这是由于形成了硼-刘易斯碱加合物。计算研究进一步支持了光物理性质和光致变色性质对噻吩间隔基和BMes 2取代位置的依赖性。
