Synthesis and Optical Properties of Hyperbranched PAEKs Containing Porphyrin and Its Metal Derivatives
THPP and its metal derivatives) were synthesized and characterized by
1
H-NMR and UV-Vis absorption spectra. The incorporation of chromophores into HPAEKs endowed HPAEKs novel NLO and OL properties. Indeed
dendritic architecture allowed for maximum dispersion of the chromophores
avoided aggregation
more optical limiting property was obtained. Simultaneously
they retained the excellent properties of the materials
particularly in thermal stability. Their optical properties were evaluated by nonlinear optical analyses and optical limiting. The results showed that these polymers possessed good optical limiting (OL) property and large nonlinear optical (NLO) susceptibilities (
