Strong supramolecular interactions, which induced tight packing and rigid molecules in crystals of cyano substituent oligo(para-phenylene vinylene) (CN-DPDSB), are the key factor for the high luminescence efficiency of its crystals; opposite to its isolated molecules in solution which have very low luminescence efficiency.
强超分子相互作用诱导氰基取代的聚对苯撑乙烯(CN-DPDSB)晶体中分子紧密堆积且呈刚性,这是其晶体具有高发光效率的关键因素;这与它在溶液中孤立分子的发光效率极低形成对比。
