Two isolated Zn-epsilon-Keggin decorated by pyridine-imidazole with excellent electrocatalytic and third-order NLO properties
Based on {epsilon-(PMo8Mo4O40Zn4)-Mo-V-O-VI} POM units, two novel organic-inorganic hybrids, [TBA](2)[(H3PMo8Mo4O40Zn4)-Mo-V-O-VI](2)[4-pyim](6)center dot 7H(2)O (1) (4-pyim = 4-(imidazol-2-yl)pyridine) and [(H3PMo8Mo4O40Zn4)-Mo-V-O-VI][2-pyim](4)center dot 3H(2)O (2) (2-pyim = 2-(imidazol-2-yl)pyridine), have been triumphantly gained under the hydrothermal conditions via self-assembly method. Compound 1 is made up of two Zn-epsilon-Keggin units jointed by two Zn-O bonds, which modified by three 4-pyim ligands, respectively, to form a dimer, while compound 2 consists of a Zn-epsilon-Keggin unit coordinated with four 2-pyim ligands. The coordination mode of the different ligands causes a change in the number of ligands coordinated on each Zn-epsilon-Keggin unit, resulting in the formation of dimers and monomers. What’s more, the third-order non-linear optical (NLO) properties of the two compounds were detected in detail due to the existence of a large number of conjugated organic ligands. Compound 1 has a superiority over compound 2 in NLO performance and the two-photon absorption (TPA) cross section (sigma) are 7320 GM for 1 and 1573 GM for 2, which is attributed to the fact that 1 own more conjugated organic ligands. The NLO testing results of compound 1 and 2 show that Zn-epsilon-Keggin unit can provide a good NLO response through combining with conjugated organic ligands, indicating that it is a wally choice for NLO materials. Furthermore, the electrochemistry properties of two compounds were also amply explored.
