A Zeolitic Organo−Metallophosphate Hybrid Material with Bimodal Porosity

The first metal carboxylatophosphate, NTHU-2, contains inorganic ZnHPO4 layers linked by BDC units (BDC = 1,4-benzene dicarboxylate or terephthalic anion); the three-dimensional anionic framework has large pores with the smallest diameter being 1.36 nm; N2 sorption isotherms reveal both micro- and mesoporosity; the new material is photoluminescent and disassembles in water wherein the discharged organic fragments form mixed crystals.

首例金属羧基磷酸盐（metal carboxylatophosphate）材料NTHU-2，其结构包含由BDC单元（BDC=1,4-苯二甲酸酯或对苯二甲酸根）桥连的无机ZnHPO4层；该三维阴离子骨架具有大尺寸孔道，最小孔径达1.36 nm；氮气吸附等温线测试结果表明，该材料同时具备微孔与介孔特性；这款新型材料具有光致发光性能，可在水中发生解离，释放出的有机片段会形成混晶。
