| Popis: | Four transition metal complexes have been synthesized via hydrothermal reactions, namely, [Zn(1,3-BIB)(CH3COO)2]2 1, [Cu2(1,4-BIB)3(CO3)2](1,4-BIB)·10H2O 2, {[Mn(H2O)2(1,2-BIB)2]Cl2}n 3, and {[Mn(1,2-BIB)(1,4-NDC)]2}n 4, where 1,n-BIB = 1,n-bis(imidazol-l-yl-methyl)benzene, n = 2, 3, 4 and 1,4-NDC = naphthalene-1,4-dicarboxylic acid. Complex 1 presents a discrete ring-like structure. Complex 2 shows a ladder-like chain structure, while complex 3 has a joint-like chain structure. Complex 4 features a layer structure constructed from [Mn2(N4O8)] clusters. The third-order nonlinear optical (NLO) properties of these complexes in thin films have been investigated by employing the Z-scan technique. Complexes 1–3 exhibit strong third-order NLO reverse-saturable absorption, while 4 shows third-order NLO saturable absorption and a strong self-defocusing effect. The third-order NLO susceptibilities χ (3) of the four complexes were calculated as 2.74 × 10−9, 12.24 × 10−9, 42.78 × 10−9 and 189.32 × 10−9 esu, respectively. The electronic structures of the complexes were investigated by density functional theory, and the origins of their NLO properties are discussed. |
