By introduction of 2,1,3-naphthothiadiazole (NT) and 2,1,3-benzoselenadiazole (BS) electron withdrawing units, a series of D-A-DⲠtype red dopants were synthesized. All of them realized saturated red emission with high fluorescent quantum yields (Φf) in non-polar toluene solutions, especially for MC6, which shows a deep red emission at 643 nm with a Φf of 0.51.
通过引入2,1,3-萘并噻二唑(NT)和2,1,3-苯并硒二唑(BS)电子萃取单元,合成了一系列D-A-Dâ²型红色掺杂剂。在非极性甲苯溶液中,所有这些掺杂剂都实现了高荧光量子产率(δf)的饱和红色发射,尤其是 MC6,它在 643 纳米波长处显示出深红色发射,δf 为 0.51。
