Abstract

We have investigated two-photon absorption(2PA) characteristics of highly efficient electroluminescent polymers, poly(phenylenevinylene) derivatives with an alkoxy and carbazole or oxadiazole groups as pendants: OxdEh-PPV and CzEh-PPV. We measured two-photon excitation spectra and compared them with one-photon excitation spectra. We found that two- and one-photon transitions satisfy different selection rules. The 2PA coefficients were obtained by measuring the photoluminescence spectra after two- and one-photon absorption. At 840nm, 2PA coefficients of OxdEh-PPV and CzEh-PPV are measured to be 1.0×10^-49cm⁴·s and 4.4×10^-49cm⁴·s, respectively.
