Imidazolium groups have been successfully incorporated into the structure of a "picket fence" porphyrin molecule to produce a novel tetra-imidazolium zinc metalloporphyrin anion receptor. UV/visible spectroscopic studies reveal that this receptor is selective for sulfate anions, capable of strongly complexing sulfate in competitive water-DMSO (5 : 95) solvent mixtures. Cyclic and square wave voltammetric studies demonstrate the receptor's ability to sense a variety of anions electrochemically.
咪唑基团已成功引入“栅栏”卟啉分子结构中，以制备一种新型的四咪唑锌金属卟啉阴离子受体。紫外/可见光谱研究表明，该受体对硫酸根阴离子具有选择性，能够在水-二甲基亚砜（5:95）竞争溶剂混合物中与硫酸根强烈络合。循环伏安法和方波伏安法研究证明了该受体具有通过电化学传感多种阴离子的能力。
