Polyphenyl glycidyl ether (PPGE) and polynaphthyl glycidyl ether (PNGE) have beensynthesized by cationic polymerization and their structures characterized by carbon 13 NMRand 1R, etc. The fluorescence spectra of PPGE, PNGE and their corresponding monomersPGE, NGE as model compounds have been studied. In dilute solutions at room temperature,only monomer fluorescence of the chromophore is observed. Comparison between the spectraobtained from dilute solutions, concentrated solutions and solid film shows that there is excimeremission when polymer chains in solution or in film are sufficiently close to each ocher.From the concentration dependence of the excimer emission, further evidence is obtained forthe existence of interchain excimer interaction in these polymers.

In dilute solutions at room temperature, only monomer fluorescence of the chromophore is observed. Concentrated between and thin films of dilute solutions, concentrated solutions and solid film shows that there is excimeremission when polymer chains in solution or in film are featured close to each ocher. From the concentration dependence of the excimer emission, further evidence is obtained forte existence of interchain excimer interaction in these polymers.
