Two novel 1,2,4,5- tetrasubstituted benzene, 1,2,4, 5-tetra (4-N, N-diphenylaminostyryl) benzene (TDASB) and 1,2, 4, 5-tetra (4-N, N-di(4"-bromophenyl) aminostyryl) benzene (TDBSB), were synthesized through Wittig-Horner reactions. Their structures were characterized by IR, NMR, MS, and melting points. The maximum absorption peaks in dichloromethane were at 400nm for TDASB and 396nm for TDBSB, respectively. The maximum emission wavelengths were at 493nm for TDASB and 491nm for TDBSB in dichloromethane, respectively. The fluorescence lifetime were 1. 7022, 3. 633ns for TDASB and 1. 2810, 4. 8473ns for TDBSB. The relationship of Stokes shift with solvent polarity was discussed.
