Abstract

Abstract : To investigate the effects of triazole-based ligands in polyoxovanadates (POVs) on proton conductivity, we designed and synthesized two decavanadate-based POVs. Abstract : Triazole, similarly to imidazole, makes a prominent contribution to the proton conductivity of porous materials. To investigate the effects of triazole-based ligands in polyoxovanadates (POVs) on proton conduction, we designed and synthesized two decavanadate-based POVs, [Zn3 (C2 H4 N4 )6 (H2 O)6 ](V10 O28 )·14H2 O (1 ) and [Zn3 (C2 H3 N3 )8 (H2 O)4 ](V10 O28 )·8H2 O (2 ) constructed from the ligands 3-amino-1, 2, 4-triazole and 1 H -1, 2, 4-triazole, respectively, via an aqueous solution evaporation method. Surprisingly, complex1 obtained a superior proton conductivity of 1.24 × 10 −2 S cm −1 under 60 °C and 98% RH, which is much higher than that of complex2 . Furthermore, due to the contribution of the conjugate properties of the ligands to the third-order nonlinear optical (NLO) properties, we also studied its two-photon responses and achieved satisfactory results.
