Three novel organic optical materials with different p electron conjugation bond structure, 4'- (N, N-dihydroxyethylamino) ,4-(pyridine-4-vinyl) stilbene (a), N-(4-N,N-dihydroxy-ethylaminobenzylidene)-4-(pyridine-4-vinyl)aniline (b), 4'-(N, Ndihydroxyethyl-amino), 4-(pyridine-4-vinyl)azobenzene (c), were prepared, their nonlinear optical properties were determined by using 8ns laser pulses at 532nm wavelength, and the relationship between p electron conjugation bond structure of molecules and nonlinear optical properties was investigated. The results show that these compounds possess large nonlinear optical properties, which are attributed to the long D-π-A conjugation structure. The nonlinear optical properties of compound with N=N double bond as conjugation bond are superior to that of compounds with C=N or C=C double bond.
