Abstract
We have investigated two-photon excited states of charge-transfer (CT) conjugated copolymers, poly(aryleneethynylene) (PAE) and poly(thiophene-alt-thiazole) (PThTz), using two-photon absorption and electroabsorption methods. The fitting analysis of the experimental spectra reveals that the two-photon excited states are located 0.5–0.6 eV above the one-photon excited states. These results are compared with nonlinear optical spectra of another CT polymer and a non-CT polymer.
