Abstract: As an important branch of porphyrin compounds，A3B-type meso-substituted unsymmetrical porphyrins have extraordinarily and remarkably diverse physical，chemical，photoelectrical and structural properties. The synthesis methods of A3B-type meso-substituted unsymmetrical porphyrins are discussed，involving the mixed aldehyde method，the “2＋2” route，the bilane route，the derivation of porphyrin route and the microwave radiation method. Accordingly，some applications of various A3B-type meso-substituted unsymmetrical porphyrins as biomimetic catalysts are elaborated. These porphyrins and their derivatives are designed，such as B-derived porphyrins which connect with other units of specific functions through the distinct meso-substituted chain，supported A3B-metalloporphyrins，A3B-metalloporphyrins dimer，Pacman bis-metalloporphyrin constructs and Hangman metalloporphyrin constructs. The future main objective of porphyrin biomimetic catalytic is to synthesize more excellent porphyrins and be used in large-scale industrial production，achieving higher enantioselectivity and larger turn-over number under mild conditions.
