A coumarin derivative bearing a [1]rotaxane structure with permethylated α-cyclodextrins suppressed unwanted solvation-induced effects and increased luminescent quantum yields in medium- and high-polarity solvents. The non-radiative decay was suppressed by the twist in the π-conjugated system and the radiative decay was enhanced by the suppression of the polarity-induced structural changes.
一种带有[1]轮烷结构的香豆素衍生物，用全甲基化的α-环糊精抑制了不必要的溶剂化诱导效应，并在中高极性溶剂中提高了发光量子产率。非辐射衰减被π共轭体系的扭曲抑制，而辐射衰减则通过抑制极性诱导的结构变化得到增强。
