The self-assembly of Zn²⁺ ion and an azolyl-carboxyl bifunctional ligand, 4,6-bis(triazol-1-yl)isophthalic acid (H₂btzip), give rise to one three-dimensional (3D) porous metal-organic framework (MOF), [Zn(btzip)(H₂O)_0.5]·H₂O (1). The MOF shows a rare (4,8)-connected scu net containing 1D channels, based on 4-connecetd ligands and 8-connected [Zn(COO)₂(H₂O)] dimers. Owing to the decoration of uncoordinated N atoms in porous walls, 1 can selectively capture CO₂ molecules over CH₄ with high adsorption heat and considerable selectivity. The different adsorption sites for CO₂ in 1 were deeply explored by simulations. In addition, 1 also displays strong solid-state luminescence that is from the intraligand charge transfer.

Zn ²⁺离子和偶氮基-羧基双官能配体4,6-双（三唑-1-基）间苯二甲酸（H ₂ btzip）的自组装产生一种三维（3D）多孔金属-有机骨架（MOF），[Zn（btzip）（H ₂ O）_0.5 ]·H ₂ O（1）。该MOF显示罕见的（4,8） -连接SCU含有1D信道，基于4- connecetd配体和8连接的[锌（COO）净₂（H ₂ O）]二聚体。由于多孔壁中未配位的N原子的修饰，1可以选择性地捕获CH ₄上方的CO ₂分子具有高吸附热和相当高的选择性。通过模拟深入研究了CO ₂ in 1的不同吸附位点。此外，1还显示出强大的固态发光，这是由于配体内部的电荷转移引起的。
