反式-[PtBr(NiDAPP)(PPh3)2](H_2DAPP=5-phenyl-10，20-bis(3‘，5‘-di-tert-butylphenyl)porphyrin)，)等外围金属化的介孔η1-铂金属卟啉的修饰，以几乎定量的产率得到了类似的铂(II)硝基和三氟代铂类亲电试剂。这些介孔铂卟啉与吡啶、4，4‘-联吡啶或各种介孔-4-吡啶基卟啉在氯仿中的自组装反应生成了新的多组分有机金属卟啉阵列，其中最多包含五个卟啉单元。这些新型的超分子阵列只在高产率下形成，并且在溶液中或在固体中长期稳定。用多核核磁共振、UV−可见光谱和高分辨电喷雾电离质谱仪对其结构进行了表征。
The modification of peripherally metalated meso-η1-platiniometalloporphyrins, such as trans-[PtBr(NiDAPP)(PPh3)2] (H2DAPP = 5-phenyl-10,20-bis(3‘,5‘-di-tert-butylphenyl)porphyrin), leads to the analogous platinum(II) nitrato and triflato electrophiles in almost quantitative yields. Self-assembly reactions of these meso-platinioporphyrin tectons with pyridine, 4,4‘-bipyridine, or various meso-4-pyridylporphyrins in chloroform generate new multicomponent organometallic porphyrin arrays containing up to five porphyrin units. These new types of supramolecular arrays are formed exclusively in high yields and are stable in solution or in the solid state for extended periods. They were characterized by multinuclear NMR and UV−visible spectroscopy as well as high-resolution electrospray ionization mass spectrometry.
