Syntheses, structures and third-order nonlinear optical properties of three coordination polymers based on bis(imidazol-l-yl-methyl)benzene and aromatic dicarboxylic ligands

Three novel transition metal coordination polymers have been reported. Their third-order nonlinear optical properties were determined by the Z-scan technique in DMSO solution. The hyperpolarizability γ′ is 1.43 × 10−29 for 1, 2.63 × 10−29 for 2 and 7.58 × 10−29 esu for 3.
