Synthesis and Characterization of Soluble Perylene Diimide Light-emitting Materials

Perylene derivatives PeryBr_2, DD-PeryBr_2 and DD-PeryBp_2 were synthesized from perylene-3,4,9, 10-tetracarboxylic acid bisanhydride and characterized by UV-Vis, FT-IR, ~1H NMR, MS, TGA and fluorescence spectroscopy measurements. The result shows that DD-PeryBp_2 is highly soluble in conventional solvents such as toluene, chloroform and THF. The UV-Vis maximal absorption and fluorescence spectroscopy maximal emission of DD-PeryBp_2 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 ℃.
