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, Zn(CHN)(HO)·14HO (1) and Zn(CHN)(HO)·8HO (2) constructed from the ligands 3-amino-1,2,4-triazole and 1-1,2,4-triazole, respectively, an aqueous solution evaporation method. Surprisingly, complex 1 obtained a superior proton conductivity of 1.24 × 10 S cm under 60 °C and 98% RH, which is much higher than that of complex 2. 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.
与咪唑类似，三唑对多孔材料的质子传导性有显著贡献。为了研究基于三唑的配体在多钒酸盐（POV）中对质子传导的影响，我们设计并合成了两种基于十钒酸盐的POV，Zn(CHN)(HO)·14HO（1）和Zn(CHN)(HO)·8HO（2），它们分别由配体3-氨基-1,2,4-三唑和1,2,4-三唑通过水溶液蒸发法构建而成。令人惊讶的是，配合物1在60°C和98%相对湿度下获得了1.24×10 S cm的优异质子传导率，这远高于配合物2。此外，由于配体的共轭性质对三阶非线性光学（NLO）性质的贡献，我们还研究了其双光子响应并取得了满意的结果。
