A novel guanidinium-templated ultraviolet (UV) nonlinear optical zinc carbonate crystal, [C(NH)]Zn(CO) (GZCO), has been synthesized in a closed system at low temperatures. GZCO crystallizing in the tetragonal noncentrosymmetric nonpolar space group, 422 exhibits a three-dimensional anionic framework constructed by interconnected [ZnCO] 12-membered ring channels with inorganic CO triangles and ZnO tetrahedra. Notably, the anhydrous GZCO shows a very high thermal stability among guanidine-based hybrid NLO materials benefiting from the confinement effect of the organic cations within inorganic channels. The UV-visible transmittance spectrum reveals that GZCO has a short UV cutoff edge of 210 nm, corresponding to the large band gap of 5.9 eV. GZCO exhibits a mild second-harmonic generation efficiency of 0.5 × KHPO with type-I phase-matching behavior.
一种新型的胍盐模板化紫外（UV）非线性光学碳酸锌晶体，[C(NH)]Zn(CO)（GZCO），已在低温封闭体系中合成。GZCO结晶于四方非中心对称非极性空间群422，呈现出由相互连接的[ZnCO] 12元环通道与无机CO三角形和ZnO四面体构成的三维阴离子框架。值得注意的是，无水GZCO在基于胍的杂化非线性光学材料中表现出非常高的热稳定性，这得益于无机通道内有机阳离子的限域效应。紫外可见透射光谱表明，GZCO具有210 nm的短紫外截止边，对应于5.9 eV的大带隙。GZCO表现出0.5×KHPO的温和二次谐波产生效率，具有I型相位匹配行为。
