Nlo Property

AbstractThe molecular structure / nonlinear optical (NLO) property relationship is explored with seven recently synthesized chromophores. Two symmetrical compounds were made using electron withdrawing groups separated by an electron rich core while five asymmetrical molecules were developed using electron donating and withdrawing groups coupled by a it electron bridging group. Pendant chains were added to some of the chromophores to improve processibility. Their syntheses are described and their optical limiting properties discussed.

Probe Measurements

Three tri-branched oligomers based on 1,3,5-triazine with large two-photon absorption cross-sections and good optical limiting properties were investigated by UV–Visible, femtosecond Z-scan and one/two-color pump-probe measurements. The two-photon absorption cross-section results measured at a wavelength of 800[Formula: see text]nm were found decreasing with the number of fluorene groups in each branches. The optical limiting properties were also investigated and a two-photon absorption mechanism was proposed. One/two-color pump-probe measurements were also used to further investigate the ultrafast responses of these tri-branched oligomers. The ultrafast response results indicated that after excitation, the tri-branched oligomers will first undergo a fast process to form an intramolecular charge transfer state followed by relaxation of the intramolecular charger transfer state of approximately several hundred ps.
