Paper Abstract

The influence of the chemical structure on the (chi) (3) of organic molecules has been selectively investigated in three poly(2,5-dialkoxy-1,4-phenylenevinylene) polymers. They have similar degrees of polymerization and polydispersity indexes and differ only for the structure of the side groups in the 2.5 positions of the phenylene rings, that are respectively C8 linear and C5 branched alkoxy chains and C12 bridged closed dialoxy chain. Z-scan measurements show that all the investigated substituted-PPVs exhibit a small Im (chi) (3) and a large, negative Re (chi) (3) at (lambda) =1064nm. The obtained results yield evidence of a considerable dependence of the third-order nonlinear optical properties on the steric effect of the substituents.
