Synthesis and characteristics of azo chromophores for nonlinear-optical application

Synthesis and characterization of three incombustible and thermostable chromophores, 1,1-dichloro-2,2-bis(4-hydroxyphenylo)ethane derivatives were done. These compounds contain azo bonds with substituted thiazole ring as side groups. The static hyperpolarizability β0 and second-order hyperpolarizability γ0 were calculated. The structures of obtained monomers were confirmed by elemental analysis, infrared, 1H NMR and ultraviolet spectroscopies. Design of nonlinear-optical polymers with included chromophores was also performed.
