An isoreticular family of seven microporous metal–organic frameworks of the general form [ZnL] have been synthesized, where L is a 4′-substituted 2,2′:6′,2″-terpyridine-4,4″-dicarboxylate ligand. Each framework adopts an interpenetrated zeolitic gismondine (gis-c) topology and possesses one-dimensional square channels with ca. 9.0 Å apertures running down the crystallographic c axis. Gas adsorption measurements with N₂, H₂, CH₄, and CO₂ confirm their permanent porosity. The ligand functional groups, which include phenyl, 2-tolyl, 4-chlorophenyl, 4-nitrophenyl, 2-thienyl, 3-thienyl, and 4-pyridyl, line the channel walls and tune the gas adsorption properties of these materials.

叔丁基羧酸盐配体衍生的等规系列锌（II）金属-有机骨架

合成了[Zn L ]形式的七个微孔金属-有机骨架的等孔网络家族，其中L是4'-取代的2,2'：6'，2”-叔吡啶-4,4”-二羧酸酯配体。每个框架均采用互穿的沸石吉斯蒙丁（gis-c）拓扑结构，并具有约一维的方通道。9.0Å孔沿晶体学c轴延伸。使用N ₂，H ₂，CH ₄和CO _2进行气体吸附测量确认其永久孔隙率。包括苯基，2-甲苯基，4-氯苯基，4-硝基苯基，2-噻吩基，3-噻吩基和4-吡啶基在内的配体官能团排列在通道壁上并调节这些材料的气体吸附性能。
