Matsuo, Shigeru published the artcileSynthesis and characterization of new fluorescent poly(arylene ether)s, Application of 3,3-Bis(4-hydroxynaphthalen-1-yl)isobenzofuran-1(3H)-one, the publication is Journal of Polymer Science, Part A: Polymer Chemistry (1994), 32(6), 1071-6, database is CAplus.
The poly(arylene ether)s were prepared by the nucleophilic aromatic substitution polymerization of phenolphthalin and its derivatives with activated aromatic difluorides. The polymers had glass transition temperatures of 210-240°. Though the monomers have no fluorescence, the resulting polymers fluoresced with a light green color in solid and solution states. The maximum excitation and emission wavelengths are 420 nm and 247 nm, resp. In the polymer solutions, the fluorescence intensity decreased gradually, but the intensity was recovered by heating the polymer at 220° for a few minutes. The fluorescent polymer had a stable radical. A model compound having the same repeating unit as the polymer was also prepared The fluorescence properties of this model were almost the same as those of the polymers.
