Microstructure and nonlinear optical characterization of a poly(aryl ether ketone) containing cobalt phthalocyanine

Abstract

Poly(aryl ether ketone) containing cobalt phthalocyanine (PAEK–CoPc) is synthesized. The resulting polymer has good solubility and thermal stability. It shows optical absorption in the visible region, and exhibits blue photoluminescence. SEM images reveal that cotton morphology is shown when a solution of PAEK–CoPc in CHCl 3 is mixed with 4 equiv of Bipy, and then dried on a substrate. The third order nonlinear optical property of PAEK–CoPc solution is characterized by Z-scan measurement at 532nm with 4.5ns pulses and the third order nonlinear optical susceptibility χ (3) is 1.11 × 10 − 11esu in the non-resonant region.
