新型经由三氮唑连接的含芘基团的杯[4]芳烃：对锌离子的比率荧光识别及其在组合逻辑门中的应用

通过“click”反应合成了两个新的由三氮唑连接的含芘的杯4]芳烃。 化合物1含有两个芘单元,对Zn2+表现出比率荧光响应,且对Cu2+, Hg2+ 和 Pb2+表现出选择性的荧光淬灭;而化合物2只含一个芘单元,对铜离子有显著的荧光淬灭,对汞离子有中等程度的荧光淬灭。利用化合物1对锌离子和铜离子不同的荧光响应,设计了INH和NOR逻辑门。

Novel Pyrene‐armed Calix[4]arenes through Triazole Connection: Ratiometric Fluorescent Chemosensor for Zn2+ and Promising Structure for Integrated Logic Gates

Two novel pyrene‐armed calix4]arenes by triazole connection were synthesized using "click" chemistry. Compound 1 with two pyrene subunits appended to the lower rims of the calix4]arene shows ratiometric fluorescence response toward Zn²⁺, and selective fluorescence quenching toward heavy metal ions such as Cu²⁺, Hg²⁺ and Pb²⁺; while compound 2 with one pyrene subunit exhibits significant fluorescence quenching toward Cu²⁺ and moderate quenching behaviour toward Hg²⁺. By utilizing the different fluorescence behavior of 1 toward Zn²⁺ and Cu²⁺, inhibition (INH) and not or (NOR) logic gates were established.
