In this paper we describe the synthesis of a new class of high glass transition temperature polyurethanes functionalized with two quasi 1D charge transfer dyes. The polymers are soluble in several organic solvents and can be processed into thin films by spinning technique. The polymers were synthesized in view of their application in second order nonlinear optics for optical signal transmission. The active chromophores, exhibiting large first hyperpolarizabilities ss(- 2 omega,omega,omega) were poled by the corona poling technique. The kinetics of poling and of relaxation were studied by second harmonic generation technique.

Abstract

In this paper we describe the synthesis of a new class of high glass transition temperature polyurethanes functionalized with two quasi 1D charge transfer dyes. The polymers are soluble in several organic solvents and can be processed into thin films by spinning technique. The polymers were synthesized in view of their application in second order nonlinear optics for optical signal transmission. The active chromophores, exhibiting large first hyperpolarizabilities ss(- 2 omega,omega,omega) were poled by the corona poling technique. The kinetics of poling and of relaxation were studied by second harmonic generation technique.
