设计并合成了一种新的不对称二芳基乙烯衍生物1-{4-（5-甲氧基-2-（2-吡啶基）噻唑基）}-2-{3-（2-甲基苯并[B]噻吩基）}六氟环戊烯（1）。由于多个结合位点的存在，I的荧光行为通过质子化、配位和光化学反应而多重转换。因此，化学和光学输入信号的合作级联了几个基本的逻辑门，在1的开放形式（10）或封闭形式（1C），10和1C中的逻辑功能是可逆的光开关。此外，光开关可逆地将逻辑功能从INHIBIT逻辑门（1C）重新配置为半触发器（1 O）。
A new unsymmetric diarylethene derivative 1-{4-(5-methoxy-2-(2-pyridyl)thiazolyl)}-2-{3-(2-methylbenzo-[b]thiophenyl)}hexafluorocyclopentene (1) was designed and synthesized. Fluorescence behaviors of I are multiswitched through protonation, coordination, and photochemical reactions due to the existence of multiple binding sites. Thus, the cooperation of chemical and optical input signals cascades several fundamental logic gates within the open form (1O) or closed form (1C) of 1, and the logic functions in 1O and 1C are reversible with photo-switch. Furthermore, photo-switch reversibly reconfigures logic functions from an INHIBIT logic gate (1C) to a half-subtractor (1O).
