Notes:
Upon ultraviolet irradiation of polygermane copolymers of methylphenylgermylene/phenylgermyne units (PhMeGe)n(PhGe)m in air, the germanium-germanium bond in the copolymer film changed into a digermoxane chain. Laser flash photolysis of the copolymer film showed the intermediacy of polygermyl radicals generated by Ge-Ge bond homolysis. The XPS showed the formation of germanium carbide (GeC) and germanium dioxide (GeO2) upon heating the unirradiated and irradiated copolymer (PhMeGe)n(PhGe)m films, respectively. A relatively high-resolution micro- pattern of GeC/GeO2 was obtained by combining the photochemical and thermal properties of the copolymers of methylphenylgermylene/phenylgermyne units. © 1997 John Wiley & Sons, Ltd.
