We demonstrate that a dipole-dipole interaction of the benzo[c][1,2,5]thiadiazole moieties, directional H-bond formation of carboxy groups, and a rigid molecular skeleton enable to yield a structurally-predictable two-dimensional hydrogen-bonded organic framework BTIA-1 from tetratopic carboxylic acid. Activated form BTIA-1a was revealed to have BET surface area of 237 m²g⁻¹ and show selective adsorption of CO₂.

通过氢键和偶极-偶极相互作用组装的二维多孔框架

我们证明苯并[ c ][1,2,5]噻二唑部分的偶极-偶极相互作用、羧基的定向氢键形成和刚性分子骨架能够产生结构可预测的二维氢-来自四元羧酸的键合有机骨架BTIA-1。显示活化形式BTIA-1a具有237m ² g ^{-1 的}BET表面积并且显示CO _{2 的}选择性吸附。
