Abstract

Abstract: The soluble fluorescent poly(aryl ether ketone) polymers were synthesized by nu-cleophilic substitution reaction of diphenol and aromatic benzene substituted by active fluo-rine.These polymers have glassy transition temperature of 210-230℃, The polymers insolid state and their solutions are all of fluorescenre with the color of green and their maxi-mum excitation and emission wavelengths are 420 nm and 487 nm respectively.The fluores-cent strengths of the polymer solution damp with time delayance, but restitute when heatedto 220℃ for several minutes.

Key words: Poly(aryl ether ketone), Fluorescence, ESR
