摘要：

本文选择Λ-型TB骨架作为分子的基本框架, 将二腈基异弗乐酮引入其中, 采用简便方法合成了一种具有聚集态荧光增强现象的红光材料2,8-双[2-(5,5-二甲基-环乙烯基-2-烯基)丙二腈]-6H,12H-5,11-甲基二苯[b,f][1,5]二氮芳辛(DMCEM). 同时, 制备了粒径不同的DMCEM纳米颗粒, 并对其光学性质进行了研究.

Abstract:

A novel Λ-shaped compound DMCEM based on Tröger′s base was designed, synthesized and its photophysical properties were examined in detail. DMCEM exhibited an aggregation-induced emission enhancement(AIEE) effect and emitted strong red fluorescence in solid states and faint fluorescence in the dilute solution. Nanocrystals of DMCEM ranging from 60 to 160 nm with well-defined spherical shape were prepared. The DMCEM naoparticles possess special size dependence on their optical properties. The red shift of the absorption and the blue shift of the emission with the increase in the particle size may be attributed to the increased rigidification of the crystal lattice and the associated decrease of vibrational relaxation.

Key words: Λ-Shaped iso-phoronederivative; Aggregation-induced emission enhancement effect; Organic-nanoparticle
