Four novel mononuclear ruthenium(II) complexes [Ru(dmb)2L]2+ [dmb = 4,4′-dimethyl-2,2′-bipyridine, L = imidazo-[4,5-f][1,10]phenanthroline (IP), 2-phenylimidazo-[4,5-f][1,10]phenanthroline (PIP), 2-(4′-hydroxyphenyl)imidazo-[4,5-f] [1,10] phenanthroline (HOP), 2-(4′-dimethylaminophenyl) imidazo-[4, 5-f] [1,10] phenanthroline (DMNP)] were synthesized and characterized by ES-MS, 1H NMR, UV-vis and electrochemistry. The nonlinear optical properties of the ruthenium(II) complexes were investigated by Z-scan techniques with 12 ns laser pulse at 540 nm, and all of them exhibit both nonlinear optical (NLO) absorption and self-defocusing effect. The corresponding effective NLO susceptibility |x3| of the complexes is in the range of 2.68 × 10−12-4.57 × 10−12 esu.
