Synthesis and characteristics of azo chromophores for nonlinear-optical application

摘要

Synthesis and characterization of three incombustible and thermostable chromophores,l,l-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 beta_0 and second-order hyperpolarizability gamma_0 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.
