以苯并咪唑-5,6-二羧酸(H3BIDC)为配体,通过水热条件下的自组装技术制备出一个三维网状结构的锌配位聚合物[Zn(HBIDC).H2O]n(1)。用X射线单晶衍射、元素分析和IR表征了1的结构,用紫外-可见吸收光谱、荧光光谱和荧光衰减曲线研究了1在DMSO溶液中和固态时的光学性能。1在室温DMSO溶液中,最大发射峰是在481nm,呈现蓝色荧光;而在固体状态下,在493nm处有一强蓝光发射峰,这均是基于苯并咪唑-5,6-二羧酸中心的单重激发态到单重基态(π*→π)的跃迁发射。实验表明1具有较高的荧光量子产率并可作为潜在的蓝色发光材料。 A three-dimensional network structure of zinc coordination polymer [Zn (HBIDC) .H2O] n was prepared by self-assembly technique under the hydrothermal conditions using benzimidazole-5,6-dicarboxylic acid (H3BIDC) (1). The structure of 1 was characterized by X-ray single crystal diffraction, elemental analysis and IR. The optical properties of 1 in DMSO solution and in solid state were investigated by UV-Vis absorption spectra, fluorescence spectra and fluorescence decay curves. 1 in DMSO at room temperature, the maximum emission peak is at 481nm, showing blue fluorescence; and in the solid state, there is a strong blue emission peak at 493nm, which are based on benzimidazole-5,6-dicarboxylic acid center Of the singlet excited state to single ground state (π * → π) transition emission. Experiments show that 1 has a higher fluorescence quantum yield and can be used as a potential blue luminescent material.
