英文摘要	Two novel, triphenylamine derivatives n-(4-(4-(diphenylamino)styryl)phenyl)acetamide and n-(4-(4-(bis-(4-(4-(diphenyl-amino)styryl)phenyl)amino)styryl)phenyl)acetamide were synthesized. the two-photon absorption of n-(4-(4-(bis-(4-(4-(diphenyl-amino)styryl)phenyl)amino)styryl)phenyl) was similar to 17-fold greater relative to n-(4-(4-(diphenylamino)styryl)phenyl)acetamide. linear absorption spectra, steady-fluorescence and time-resolved fluorescence spectra revealed that electron coupling originating from pi-electron delocalization is responsible for the strong cooperative enhancement of tpa within the compounds. this is confirmed by the lippert-mataga equation.
