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 ℃.
