Notizen: A meltable, partially crystalline silane copolymer, PSN, containing dimethylsilylene and methyl(1-naphthyl) silylene units was synthesized and characterized. The polymer has a high molecular weight, is appreciably soluble in common solvents and is photoactive. The emission properties of PSN, under stationary and nonstationary conditions, were studied in dilute THF solution. PSN is the first organosilane polymer showing an intense intramolecular excimer emission in addition to monomer and intramolecular charge transfer (CT) fluorescence. It is shown that the ratio of excimer to monomer fluorescence can be used to monitor the UV induced degradation of the polymer.
