摘要：

Two novel Ru-II complexes [Ru(phen)(2)(PNOPH)](2+) and [Ru(dmp)(2)(PNOPH)](2+) (phen = 1,10-phenanthroline, dmp = 2,9-dimethyl-1,10-phenanthroline, PNOPH = 2-(4-nitrophenyl)imidazo-[4,5-f][1,10]phenanthroline) and their deprotoned complexes were synthesized and characterized by ES-MS, H-1- n.m.r, u.v.-vis. and electrochemistry. The crystal structure of the deprotonated complex [Ru(dmp)(2)(PNOP)][ClO4].CH3CN was determined by means of X-ray single crystal diffraction. Nonlinear optical properties of the RuII complexes were investigated by Z-scan techniques in DMF solution, and all of them exhibited both NLO absorption and self-defocusing effect. The corresponding effective NLO susceptibilities \chi(3)\ of the complexes are 2.39 x 10(-12)-5.80 x 10(-12) esu.
