Abstract

Novel functional poly (aryl ether ketone)s bonded nonlinear optical chromophores (meso-tetrakis (4-hydroxyphenyl) porphyrin, THPP) with different backbone structures were synthesized and characterized using proton nuclear magnetic resonance, Fourier transform infrared, and ultraviolet–visible absorption spectra. Their optical properties were evaluated by nonlinear optical analyses and optical limiting (OL). The results showed that these polymers possessed good OL properties and large nonlinear optical (NLO) susceptibilities. All polymer films-containing THPP presented excellent thermal stability (>460°C). Polymers bonded with –CH3 to the backbone exhibited better performances in OL and NLO properties than those bonded with –CF3 ; however, the thermal stability of the former was slightly inferior. Backbone bonded with electron donating groups was conducive to the OL and NLO properties.
