Abstract
Novel 2D organic-inorganic hybrid perovskites, including (4-CF—PMA)PbI, that emit in the blue spectral region, and methods for making same. The CF-substituted material exhibits a ˜0.16 eV larger bandgap than corresponding halogen-substituted materials. This family of materials offers a degree of freedom in tuning 2D perovskites to specific bandgaps for optoelectronic applications. These materials are highly stable, easily synthesized, and do not suffer from phase separation.
