Synthesis of novel self-organized organic/inorganic layered compound usinga quaternary dialkylammoniun

A novel self-organized organic/inorganic hybrid compound was synthesized by means of dilauryldimethylammonium bromide and lead bromide as organic cati on and metal halide, respectively. The synthesized compound was characteriz ed by X-ray diffraction and optical measurements. The powder X-ray diffract ion patterns indicated that the synthesized compound had a two dimensional layered structure. Spin-coated films were easily prepared from chloroform s olutions of the compounds. After the film preparation, a polycrystalline st ructure that showed the same X-ray diffraction pattern as that of a powder sample, is observed to form by self-organization. The spin-coated film had an absorption band at around 352.5 nm that corresponded to self-organized i norganic region. The fluorescence measurement for the powder sample showed a fluorescence band that was assigned to the inorganic structure. These str uctural and optical measurements suggested that a novel quantum confined st ructure was constructed with the compound.
