摘　　要：A novel Λ-shaped compound DMCEM based on Trger′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.A novel Λ-shaped compound DMCEM based on Trger′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.
