戊间二烯

The kinds of compounds with AIE, AIEE and CIEE are summarized, mainly including siloles, substituted ethenes (mainly including fulvene and DPDSB style), CN-MBE, pyran, biphenyl compounds and polymers.

侧重总结了silole型、取代乙烯型（主要包括亚甲基环戊二烯型和DPDSB型）、腈取代二苯乙烯型、吡喃型、联苯型等小分子化合物和少数高分子的结构与AIE性质之间的关系，以及为解释AIE现象所提出的限制分子内的转动、避免非辐射去活、构象扭曲避免形成excimer、J－聚集态以及形成分子间的C-H/π键等理论。
