Zr-IV盐和卟啉四羧酸之间的反应导致具有两种类型的开放通道的金属-有机框架（MOF），表示具有（4，8）-连接的sqc网的MOF。MOF在沸水和pH范围为1至11的水溶液中保持完整，这是MOF可以维持的非常广泛的pH范围。由于其优异的稳定性和pH依赖性的荧光强度，MOF可以潜在地应用于荧光传感。
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 sensing.
