Abstract

ABSTRACT: A series of novel soluble poly(aryl ether ketone)s (PAEKs) based on 5, 10‐ bis (4‐hydroxyphenyl)−15, 20‐diphenylporphyrin ( cis ‐DHTPP), 4, 4′‐(hexafluoroisopropylidene) diphenol (6FBPA) and 4, 4′‐difluorobenzophenone (DFB) were synthesized and characterized by FT‐IR, 1 H‐NMR, UV–vis and fluorescence spectroscopies. The intrinsic photophysical properties of porphyrins were preserved because of the absence of photoinduced electron transfer in the polymer chains. Investigation of the copolymers thermal properties indicated that these polymers had high glass transition temperatures and excellent thermal stabilities. The results of Z ‐scan and optical limiting measurements manifested that incorporation of the porphyrin chromophore into the main chain engendered the novel PAEKs with superior nonlinear optical properties and optical limiting function, which could be effectively tuned by varying the molar ratio of porphyrin monomers. © 2014 Wiley Periodicals, Inc.

Chem. 2014, 52, 1282–1290 Abstract : A series of novel poly(aryl ether ketone) (PAEK) copolymers containing porphyrins in the main chain have been designed and synthesized successfully. The porphyrins units endow PAEKs with a strong fluorescence response, large third‐order nonlinear susceptibilities, and excellent optical limiting performance. The improved thermal stabilities and glass transition temperature as a result of the incorporation of porphyrins in the backbone are also investigated.
