Abstract
A series of copoly(2,3,5,6-tetrafluoro-1,4-phenylenevinylene-2,5-dioctyl oxy-1,4-phenylenevinylene)s containing variable ratios of tetrafluorophenylenevinylene and dialkoxyphenylenevinylene repeating units has been synthesized via the Stille cross-coupling reaction in order to investigate the influence on the (chi) (3) of the simultaneous presence of electron-deficient and electron-rich aromatic monomers in the PPV backbone. Third-order nonlinear optical properties of the resulting materials have been studied in chloroform solutions at (lambda) =1064 nm using the picosecond Z-scan technique. The nonlinear refractive index has been found to be negative, strongly dependent on the copolymer composition, and as high as (-10+/- 2)x10-12cm2/W.
