characterization of substituted 5,15-bis-(4′-hydroxy-3′,5′-di-tert-butyl-phenyl)-porphodimethenes (3a-b), are described. Spectroscopic studies of redox-active 3,5-di-tert-butyl-4-hydroxyphenyl substituted porphodimethene 3a, 3b reveal a change in conformation via acid/base-switched tautomerism by simultaneously switching between porphodimethene and porphyrinogen accompanied by visible chromogenic changes. The novel
合成和取代的5,15-双- (4'-羟基-3',5'-二-表征叔丁基-
苯基)-porphodimethenes(3A-B ),进行说明。
氧化还原活性的3,5-二叔丁基-
4-羟苯基取代的
二甲亚砜3a,3b的光谱研究通过同时在
二甲亚砜和
卟啉原之间切换并伴有明显的生色变化,揭示了通过酸/碱切换互变异构构象的变化。新型原型显示出正溶剂溶剂致变色,并显色检测
氟化物(特别是在极性溶剂中)和
氢氧根离子(在所有溶剂中)。独特的结构变化以及明显的颜色变化通过UV-Vis,荧光,循环伏安NMR光谱技术和DFT计算进行监测。
