The third order nonlinear susceptibility, χ(3), of a π-conjugated polymer with an open-shell configuration, poly(4-(3′,5′-di-tert-butyl-4′-oxyphenyl)-1, 2-phenylene-vinylene), was measured with a z-scan method. The real and imaginary parts of χ(3) for the open-shell polymer were enhanced three orders of magnitude at ca. 700 nm.
