We describe the synthesis of mono- and bis([6]helicene-≡-Ru(dppe)2-≡)-DTE complexes 1o,c and 2o,c. The photochromic and electrochromic properties were studied, and attractive isomerization processes were observed, i.e., spontaneous reopening of [1c]•+ to [1o]•+ and ring closure of [2o]2+ to [2c]2+. Due to strong chiroptical responses, all of these chiral complexes correspond to new types of chiroptical switches (triggered by light and/or redox stimuli) and could be described as either “NOR” or “OR” logic gates.

十六烷和双乙炔基钌单元修饰的光致变色二噻吩乙烯中的双氧化还原和光学控制的手性。

我们描述了单-和双([6]≡-Ru-Ru(dppe)2 -≡ )-DTE配合物1o,c2oc的合成。研究了光致变色和电致变色性质,并观察到了有吸引力的异构化过程,即[ 1c ] •+自发重开至[ 1o ] •+和[ 2o ] 2+至[ 2c ] 2+闭环。由于强烈的手性响应,所有这些手性络合物都对应于新型的手性开关(由光和/或氧化还原刺激触发),可以描述为“或”或“或”逻辑门。
