Organic-inorganic hybrids based on the layered perovskite framework ([CH_3(CH_2)_<17>NH_2]_2PbI_4 and [CH_3(CH_2)_<17>NH_2]_2PbCl_4) have been naturally formed by intercalating lead hallide into organic (alkylammine) Langmuir-Blodgett films. Only diffraction peaks corresponding to (0 0 n) of the layered perovskite were observed in the X-ray diffraction pattern of the deposited film. X-ray diffraction measurement demonstrated that the layer structure is oriented parallel to the film plane. The deposited film showed sharp and strong UV-Vis absorption at 390nm, which is charactristic of Wannier exciton in lead halide-alkylammonium multi-layered perovskites, thus demonstrating the formation of the layered perovskite structure.
