The research presented here focusses on fabrication of organic modified inorganic two-dimensional and three-dimensional materials via microwave assisted methods. These hybrid materials are of importance due to their capacity to incorporate the characteristics of both organic and inorganic components. Microwave methods have been utilized to expedite the topochemical modification of layered perovskites. In one set of studies, microwave assisted grafting reactions were performed on layered perovskite (HLaNb2O7) materials with a series of hydroxy carboxylic acids. The reactivities of these organic compounds with the layered perovskites and the influence of precursor, temperature and time are demonstrated. The hydroxy carboxylic acid grafted perovskites show interesting optical properties which were investigated using UV-Vis spectroscopy. In addition to inorganic-organic perovskite fabrication, an exfoliation-restacking procedure was performed on double and triple layered Dion-Jacobson phases (HLaNb2O7 and HCa2Nb3O10 respectively). Homogenous and heterogenous restacking procedures were performed and then compared with constructed models. Apart from grafting with hydroxy carboxylic acids, surface modification of Dion-Jacobson phases using a diol (hydroquinone) were performed on two-dimensional nanosheets and three-dimensional layered materials using both microwave and benchtop methods. The inorganic-organic hybrid materials investigated are demonstrated to have bilayer arrangement in the interlayer. Furthermore, structural refinement of HLaNb2O7 was performed using neutron diffraction data to identify the position of hydrogen in the interlayer.
