Polysilane Dendrimer. Synthesis and Characterization of [2,2-(Me3Si)2Si3Me5]3SiMe

The entitled compound was synthesized by using a step-growth polymerization technique and its molecular structure was determined by X-ray crystallography. This dendrimer showed a distinct UV absorption maximum at 264 nm and exhibited two very feeble fluorescence maxima at 320 nm and 400 nm.
