Abstract
The results of experiments aimed at studying the concentration dependences and the time and temperature stability of the quadratic response of guest-host type materials based on polycarbonate and original synthesized dyes are presented. It is shown that modifications of the chromophore by dendronic side substituents significantly improve the solubility, which allows construction of polymer materials with a high content of optically active particles. The materials have high time and temperature stability and exhibit d33 up to 80 pm/V at a chromophore concentration of 2.5.1020 cm-3.
