Abstract : A pseudo-one-dimensional poly-yne polymer (I) in which phthalocyanine silicon (PcSi) moities are bridged by p-diethynyl benzo groups has been obtained by salt elimination reaction from dichloro phthalocyaninato silicon and the disodium salt of p-diethynyl benzene in tetrahydrofuran (THF) solution. A soluble mixture of short chain oligomers of this polymer was also obtained. For parallel study, an analogous low dimensional poly-yne polymer (III) was synthesized by reaction of dimethyl dichloro silicon with disodium salt of diethynyl benzene in either solution. Materials (1) and (III) were found to be stable in air and have good thermal stability. These two polymers were characterized by spectral and analytical data. (Author)
