Triazole and triazolium groups have been integrated into a zinc(II) metalloporphyrin-based structural framework to produce two porphyrin-cages for anion sensing applications. UV/visible spectroscopic titration investigations reveal both host systems exhibit strong anion binding affinities, with the positively-charged triazolium-porphyrin cage capable of colorimetric sensing halides, fluoride and chloride, and oxoanions in acetone-water solvent mixtures.
三唑基和三唑鎓基团已被整合到基于锌(II)金属卟啉的结构框架中，以产生两种用于阴离子传感应用的卟啉笼。紫外/可见光谱滴定研究表明，这两个主体系统都具有很强的阴离子结合亲和力，带正电荷的三唑鎓卟啉笼能够在丙酮-水溶剂混合物中比色传感卤素、氟化物和氯化物以及含氧阴离子。
