GeneralLaboratoryMethodsforTetrapyrroles
There are thousands of porphyrins and metalloporphyrins, and hundreds of new derivatives appear each year. This variety arises because the cyclic conjugated tetrapyrrole nucleus (Figure 1 ) can have different substituents at the eight β-pyrrole positions, at the four meso [5,10,15,20] carbon atoms, and N-alkyl groups can be added to the four central nitrogen atoms. Since its synthesis in 1972, over 8000......阅读全文
