Organic - inorganic assembly layered perovskite - type materials integrate useful organic and inorganic characteristics on a molecular level . the inorganic component forms an extended framwork bound by strong covalent or ionic interactions , and the organic component is filled in which and thus the organic layer and inorganic layer are alternately stacked . the materials have unique properties such as electronic , optic and magnetic properties , and there has been great interest in studying them recently 層狀類鈣鈦礦有機-無機分子組裝材料在分子水平上結合了有機組分和無機組分的有益特性,無機組分通過強的共價鍵或離子鍵形成擴展的骨架,并將有機組分填入框架中形成有機層與無機層交替的結構,具有某些電學、光學、磁學特性,引起人們的研究興趣。
