A photochromic bisthienylethene derivative (BIT) containing two imidazole units has been synthesized and fully characterized. When triggered by chemical ions (Ag(+)), protons, and light, BIT can behave as an absorbance switch, leading to a multiaddressable system. BIT exhibits sequence-dependent responses via efficient interaction of the specific imidazole unit with protons and Ag(+). Furthermore, an INHIBIT logic gate and a keypad lock with three inputs are constructed with the unimolecular platform by employing an absorption mode at different wavelengths as outputs on the basis of an appropriate combination of chemical and photonic stimuli.
一种含有两个咪唑单元的光致变色双噻吩乙烯衍生物（BIT）已经被合成并进行了全面的表征。当被化学离子（Ag(+））、质子和光触发时，BIT 可以作为一个吸光度开关，从而实现一个多地址系统。BIT 通过特定的咪唑单元与质子和 Ag(+）的有效相互作用表现出序列依赖性响应。此外，基于适当的化学和光子刺激的组合，通过采用不同波长的吸收模式作为输出，使用单分子平台构建了一个具有三个输入的 INHIBIT 逻辑门和一个键盘锁。
