been realised. Additionally, the spiropyran ring-opening↔closing reactions of two skeletally identical spirobenzopyrans 4 and 5, but possessing "electronically-modifying" 5-trifluoromethyl-substitutents have been studied by 1 H NMR spectroscopy: this has enabled us to realise the additional biasing, on the ring-opening↔closing process, excerpted on these systems through both selectively placed, inductively
已经证明了使用光致变色取代螺苯并吡喃在界面上进行 Zn 2+ 离子的光可逆传输。研究了战略性放置的空间影响 3'-methyl-3b 和 3-spirocyclohexyl-3c 组的包含,并与未取代的类似物 3a 进行比较。对螺吡喃开环↔闭环反应的显着控制,从而实现了 Zn 2+ 离子传输。此外,通过 1 H NMR 光谱研究了两个骨架相同的螺苯并吡喃 4 和 5 的螺吡喃开环↔闭环反应,但具有“电子修饰”5-三氟甲基取代基:这使我们能够实现额外的偏置,在开环↔闭环过程中,通过选择性放置,在这些系统上摘录,
