摘　　要：通过简单的合成策略制备出具有聚集诱导发光性质的邻碳硼烷-N-苯基咔唑区位异构体化合物(C3DC和C9DC),并对其结构进行了表征.两种化合物均具有聚集诱导发光性质,固态下化合物C3DC和C9DC的发光量子产率分别高达99%和93%.DFT理论计算结果表明,化合物的发光主要源于分子内邻碳硼烷与咔唑之间产生的分子内电荷转移.This work described here a new design strategy for obtaining o-carboranyl compounds containing regioisomeric N-phenyl-carbazole with AIE properties.Two o-carborane functionalized N-phenyl-carbazole compounds(C3DC and C9DC)were synthesised and fully characterised.Photoluminescence experiments confirmed both compounds have strong AIE activity.The two o-carborane-functionalised N-phenyl-carbazole isomers have high solid-state fluorescence quantum yields,reaching 99%and 93%,respectively.In addition,based on the results of DFT calculation,the emission bands could be attributable to ICT transitions from N-phenyl-carbazolemoieties to the o-carborane units.
