Topochemical modification of layered perovskites by microwave assisted methods allows for the rapid introduction of organic substituents. Dion-Jacobson double layered perovskites (e.g., RbLaNb2O7) can be used for the synthesis of various n-alkyl grafted perovskites. Following proton exchange of the layered perovskite, reactions can readily occur with organic precursors containing hydroxyl substituents where the organic grafts to apical oxygens within the perovskite interlayer. In this study a series of organics with combinations of hydroxyl, carboxylate, and aryl groups were investigated to gauge the influence of the carboxylate and aryl groups on both reaction and grafting orientation. Details on the synthesis and structures of various new inorganic-organic hybrids will be presented and the influence of the different molecular components discussed.
