Paper Abstract

A novel cross-linked second-order nonlinear optical polyurethane was synthesized from disperse red 19 (DR-19), triethanolamine and the trimer (TTDI) of toluene diisocyanate. The thermal stability of the polyurethane was significantly improved because the trimer had high thermal stability and increased the cross-link degree and the rigidity of the polyurethane. The polyurethane obtained high poling efficiency through a novel "host-guest" approach, and the electro-optical coefficient γ33 reached 37 pm/V at 832 nm. The propagation loss of the polyurethane was lowered because the number density of C-H bonds in the polyurethane was low and the films had good optical quality.
