What is Syntheses, characterization and third-order nonlinear optical properties of ruthenium(II) complexes containing 2-phenylimidazo-[4,5-f][1,10]phenanthroline and extended diimine ligands about?

Four novel ruthenium(II) complexes [Ru(PIP) 2 L] 2 + [PIP=2-phenylimidazo-[4,5-f ][1,10]phenanthroline, L =1,10-phenanthroline (phen), 1,4,8,9-tetra-aza-triphenylene (tatp), dipyrido[3,2-a:2%,3%-c]phenazine (dppz) and benzo[i ]dipyrido[3,2-a:2%,3%c]phenazine (dppn)] have been synthesized and characterized. The electrochemical behaviors of these complexes have been studied in acetonitrile by cyclic voltammetry. The nonlinear optical properties of the ruthenium(II) complexes were investigated by Z-scan techniques with 12 ns laser pulses at 540 nm, and all of them exhibit both NLO absorption and self-defocusing effect. The corresponding effective NLO susceptibility 3 of the complexes is in the range of 4.78-8.49 × 10 -12 esu. The results indicate that the extension of the p-framework of the ligands has an effect on the NLO properties of the complexes.
