ABSTRACT
An effective microwave approach to the topochemical modification of different layered oxide perovskite hosts is presented where cation exchange, grafting, and intercalation reactions with acid, n-alkyl alcohols, and n-alkylamines, respectively, are successfully carried out. Microwave-assisted proton exchange reactions involving double- and triple-layered Dion-Jacobson and Ruddlesden-Popper perovskite family members, RbLnNb2O7 (Ln = La, Pr), KCa2Nb3O10, Li2CaTa2O7, and Na2La2Ti3O10, were found to be quite efficient, decreasing reaction times from several days to ≤3 h. Grafting and intercalation reactions involving double-layered perovskites were also quite rapid with full conversions occurring in as fast as an hour. Interestingly, triple-layered hosts were found to show different behavior; when complete intercalations were possible, grafting reactions were limited at best. Utilization of this rapid synthetic approach could help facilitate the fabrication of new organic-inorganic hybrids.
