that the repeatable movement of the hemithioindigo, so-called the hemithioindigo shuttle, between two kinds of porphyrins was controlled by the photoirradiation. These movements were applied to create a molecular switch for changes in the quinone distribution between two kinds of porphyrins.
当2-(3'-吡啶基亚甲基)-7-乙基苯并[光致变色b ]噻吩-3-(2- ħ) -酮(4)进行了研究,高的热的稳定性Ë的异构体4,4(ë)和良好的发现了光诱导的E,Z-异构化的可重复性。的1的缔合常数:1个complexations的4(Ž)和4(ë)与ureidoporphyrin 1和与pentafluorobenzamidoporphyrin 2进行了评价。我们发现1优先于捕获4(E)4(Z),相反,2则更喜欢4(Z)而不是4(E)。基于这些结合能力的差异,我们得出结论,半卟啉靛蓝(所谓的半硫靛蓝穿梭)在两种卟啉之间的可重复运动是受光辐照控制的。应用这些运动来创建分子开关,以改变两种卟啉之间的醌分布。
