A reaction between a Zr(IV) salt and a porphyrinic tetracarboxylic acid leads to a metal-organic framework (MOF) with two types of open channels, representing a MOF featuring a (4,8)-connected sqc net. The MOF remains intact in both boiling water and aqueous solutions with pH ranging from 1 to 11, a remarkably extensive pH range that a MOF can sustain. Given its exceptional stability and pH-dependent fluorescent intensity, the MOF can potentially be applied in fluorescent pH sensing.
Zr(IV) 盐和卟啉四羧酸之间的反应生成了一种具有两种类型开口通道的金属-有机骨架（MOF），代表了具有（4,8）连接 sqc 网络的 MOF。该 MOF 在沸水和 pH 值范围从 1 到 11 的水溶液中均保持完整，这是一个 MOF 可以承受的非常广泛的 pH 范围。鉴于其出色的稳定性和 pH 依赖性荧光强度，该 MOF 有可能应用于荧光 pH 传感。
