在水热条件下合成了一种新的三维锌-有机骨架[ZnL]·5H2O （1,k2l = 4′-呋喃-2,2′：6′，2″-三吡啶-4,4″-二羧酸盐）。配合物1具有2重互穿4连接的三维网状结构，孔隙由非配位呋喃环修饰，在450nm处具有较宽的蓝色发光发射带。由于l2配体中trepyydyl基团的螯合作用和Zn（II）上没有溶剂配位，配合物1表现出良好的耐热和耐酸稳定性，可在1000℃氩气气氛下直接炭化成新型微孔碳材料c1000。通过对氮气和co2的吸附测定，研究了脱溶碳和微孔碳的气体吸附性能。
A new 3D zinc-organic framework of [ZnL]·5H2O (1, K2L = potassium 4′-furyl-2,2′:6′,2″-terpyridine-4,4″-dicarboxylate) has been synthesized under hydrothermal conditions. Complex1possesses a 3D 2-fold interpenetrated 4-connectedsranetwork with pores decorated by noncoordination furan rings, and it exhibits a broad blue luminescence emission band peaked at 450 nm. Due to the chelating effect of trepyridyl moieties in L2–ligands and the absence of solvent coordination sites on Zn(II), complex1exhibits a good thermal and acid-proof stability, and can be directly carbonized at 1000 °C under argon atmosphere into a new microporous carbon materialC1000. The gas adsorption properties of desolvated1aand microporous carbonC1000have been studied by N2and CO2sorption measurements.
