Abstract:

Perylene derivatives PeryBr2， DD-PeryBr2 and DD-PeryBp2 were synthesized from perylene-3,4,9,10-tetracarboxylic acid bisanhydride and characterized by UV-Vis, FT-IR, 1H NMR, MS, TGA and fluore-scence spectroscopy measurements. The result shows that DD-PeryBp2 is highly soluble in conventional solvents such as toluene, chloroform and THF. The UV-Vis maximal absorption and fluorescence spectroscopy maximal emission of DD-PeryBp2 are at 548 nm and 576 nm, respectively. TG measurements show that perylene diimides possess good thermal stability and the temperature at which 5% mass loss is observed in nitrogen is 433 ℃.

Key words: perylene diimides,solubility,thermal stability,light-emitting material
