Systematic study on the optimization of a bis(N,N-diethyl)aniline based NLO chromophore via a stronger electron acceptor, extended π-conjugation and isolation groups

Abstract

New chromophores which contains the optimal structure of the same bis(N,N-diethyl)aniline donor were synthesized and the hyperpolarizability β can be effectively translated into large electro-optic coefficients in poled polymers.
