Abstract: Organic-inorganic assembling lay ered perovskite-type materialsint egrate organicand inorganic characteristicson a mole cular level.The inorganic component forms an extended framework bound by strong covalent or ionic int eractions,which is filled with the organic component,and thus the organic layer and inorganic layer are alternately stacked.The materialshave unique properties such as electronic,opticand magnetic properties.The structure and relative properties of organic-inorganic assembling layered perovskite-type materials were briefly reviewed.
