The intramolecular excited state interaction between phenol and styrene in a series of trans-2-cinnamylphenols bearing electron-donating substituents at the phenolic ring has been directly observed as an exciplex emission in acetonitrile. The photochemical reactivity and the relatively low fluorescence quantum yields as compared with model compounds are additional evidences for the phenol/styrene interaction
已直接观察到一系列在酚环上带有给电子取代基的反式-2-肉桂基苯酚中苯酚和苯乙烯之间的分子内激发态相互作用,作为乙腈中的激基复合物发射。与模型化合物相比,光化学反应性和相对较低的荧光量子产率是苯酚/苯乙烯相互作用的其他证据。
