Non-radiative excitation energy transfer from a statistic copolymer to acceptor in fluid solutions
The measurements of the efficiency of non-radiative energy transfer (NET) from a statistic copolymer styrene-methyl methacrylate (donor) to 1,1,4,4-tetraphenyl-1,3-butadiene (acceptor) were carried out in 1,2-dichloroethane to investigate dependence on the acceptor concentration. Marked increase in the transfer efficiency, η, with growing styrene content (fM) in a copolymer was observed, this being evidence of the energy migration along copolymer chain. The drop in efficiency η observed in systems with fM>0·7 was accounted for by the presence of intramolecular excimers. Good agreement was found between the experimental results and the proposed model for NET in the systems investigated.
