N-混乱卟啉（NCP）的Ni（II）、Pd（II）和Cu（II）配合物通过混乱吡咯环的NH位上的氢键相互作用表现出阴离子结合性质。四（五氟苯基）-NCP金属配合物（1-M，M= Ni，Pd，Cu）在CH_2Cl_2中对各种卤阴离子的结合常数分别按F-> Cl-> Br-> I-的顺序增加。两性离子共振形式的NCP配合物以及卤素阴离子和五氟苯基之间的相互作用被认为是重要的有效的阴离子结合。
Ni(II), Pd(II), and Cu(II) complexes ofN-confused porphyrin (NCP) exhibit anion binding properties through a hydrogen bonding interaction at the peripheral NH of confused pyrrole ring. The binding constants of the tetrakis(pentafluorophenyl)-NCP metal complexes (1-M,M= Ni, Pd, Cu) for various halide anions in CH2C12increase in the order of F−> Cl−> Br−> I−, respectively. Zwitterionic resonance form of the NCP complexes as well as interactions between halide anions and a pentafluorophenyl group are suggested to be important for efficient anion binding.
