摘要：

Since the first observation of an efficient resonant energy transfer between polydihexylsilane and polydiphenylsilane, we have studied the energy transfer and radiative properties of polysilanes and their energy-matched counterparts. The synthesis of soluble polysilanes enabled us to prepare such pairs in a thin film simply by a spin-coating technique. The intermolecular energy transfer from conductive poly(m-hexoxyphenyl)phenylsilane was utilized for electroluminescence (EL) of perylene (blue), coumarin 6 (green), 4-(dicyanomethylene)-2-methyl-6-(p-dimethylaminostyryl)-4H-pyran and Zinc tetra-phenylporphyrin (red). A white EL was also observed by mixing four dye molecules. Photo-oxidation during irradiating an ultraviolet light was suppressed by synthesizing water-soluble polysilanes and embedding it inside sol-gel glass matrices. These results imply that polysilanes have a possibility to open new fields of optical applications. (C) 2003 Elsevier B.V. All rights reserved.
