Abstract: Porphyrins are an important large class of macro-cyclic compounds, and exist extensively in nature and living bodies. The unique chemical structure of porphyrins endows them with superior physical, chemical and optical properties that make them to have broad applications in many fields. However, free porphyrins have intrinsic limitations, e.g., poor chemical stability, ir-reusability, processing difficulty and so on. These limitations hinder their applications greatly. The natural porphyrins usually coexisted with some specific natural macromolecules. Under certain conditions, porphyrins could fully exert their functions. Accordingly, many suitable materials have been developed to immobilize porphyrins and metalloporphyrins in order to overcome the defects of free porphyrins described above and expand their applications. In this review, the common carriers of porphyrins, the usual methods for immobilizing porphyrins, and the latest application of immobilized porphyrin compounds in catalysis, sensor, and so on have been summarized. The application prospectives of immobilized porphyrins is also presented.
