    • The fluorescence lifetime of the corresponding monomer was employed as the standard (ref 18) to estimate the rate constant of the fluorescence decay of chromophores in copolymers 2. The environment of the chromophore in 2 may be different from the corresponding monomer in solution. There is possibility that self-quenching may occur in 2 because of folding. However, it is known that intrachain chromophore-chromophore interactions are important only if the persistent length of the conjugated system is relatively short (e.g, divinylbenzene, refs 5a and 5d, In outer words, when the persistent length is long, the emission profiles of the silylene-spaced divinylarene copolymers are very similar to those of the corresponding monomeric chromophores ref 5d, In this regard, self-quenching might not be important
