Abstract
Weakly electron withdrawing bromine substituted poly(2-bromo-1,4-phenylenevinylene) (PBrPV) was synthesized th-rough water-soluble precursor method. The linear and nonlinear optical properties of PBrPV were compared with those of poly(1,4-phenylenevinylene) (PPV). The third-order nonlinear optical susceptibility, χ(3), was measured by using third-harmonic generation (THG) technique at 1907 nm, fundamental wavelength. The calculated χ(3) values of PPV and PBrPV were 3× 10-12 esu and 2×10-12 esu, respectively.
