methylphosphonate underwent intramolecular (4+4) photocycloaddition between two anthryl groups. The fluorescence spectra of the naphthyl derivatives had two emission bands ascribed to an intramolecular excimer and a monomer, but the fluorescence spectra of the anthryl derivatives had only a monomer emission band. These photoluminescence behaviors are closely related to the reactivities of the compounds.
在乙腈中紫外线照射下,磷酸三-1-萘酯和甲基膦酸二-1-萘酯发生分子内重排和ipso偶联,分别得到1,2'-联萘-1'-醇和1,1'-联萘。在三(4-甲氧基-1-萘基)磷酸酯和双(4-甲氧基-1-萘基)甲基膦酸酯在甲醇中的光解中,4,4'-二甲氧基-1,1'-联萘,1',4,4生成'-三甲氧基-1,2'-联萘和2,4,4'-三甲氧基-1,1'-联萘。Tri-9-anthryl phosphate 和 di-9-anthrylmethylphosphonate 经历了两个蒽基之间的分子内 (4+4) 光环加成。萘基衍生物的荧光光谱有两个来自分子内准分子和单体的发射带,而蒽基衍生物的荧光光谱只有一个单体发射带。
