We report the synthesis and characterisation of [2]rotaxanes based on a stilbazolium dye and a calix[6]arene macrocycle. Since both components are non-symmetric, two orientational isomers are obtained. The two isomers display distinct photophysical and photochemical properties in solution and solid state, superior to the unencapsulated dye.
我们报告了基于芴酮染料和杯[6]芳烃大环的[2]轮烷的合成与表征。由于两个组成部分都是不对称的，因此得到了两种取向异构体。这两种异构体在溶液和固态中表现出不同的光物理和光化学性质，优于未封装的染料。
