Fluorescence Properties of Anthracene-Polyvinyltoluene System. Effects of the Copolymerization of Anthracene

Fluorescence properties of anthracene-polyvinyltoluene system in which the incorporation of anthracene molecule in polymer chain is possible by copolymerization have been studied under various conditions. It was found that the fluorescence spectra of this system changed remarkably depending on the anthracene concentration, excitation wavelength and temperature. Most of these spectral changes may be attributed to the effect of the copolymerization of anthracene in polymer chain and not to a trivial reabsorption effect. Influence of this effect on the nonradiative energy transfer has also been examined by spectral shape analysis. It seems to decrease transfer efficiency slightly rather than to improve it in this system.
