ABSTRACTThe synthesis of three types of functionalized benzazole structures is described. A centrosymmetric dihydroxy-benzobisthiazole has been synthesized for incorporation in flexible polymers having rigid, conjugated, third order nlo active units in the main chain. Benzazole structures terminated with an N,N-dimethylamino group and a carboxyl group have been synthesized for use as second order nlo pendants with flexible polymers. Benzazole structures terminated with an N,N-dimethylamino group and an amino group have been synthesized as precursors to second order nlo guest molecules.

We quantitatively investigate the nonlinear optical (NLO) property of carbon nanodots (CNDs, less than 10 nm) by the Z-scan technique using a tunable 532 nm nanosecond laser system.

The Third

The third-order nonlinear optical properties of the N-6-hydroxy-hexyl-4-azophenyl-carbazol have been investigated both theoretically and experimentally. Using Z-scan method with a femtosecond laser (440[Formula: see text]nm, 190[Formula: see text]fs), the third-order nonlinear optical properties of the N-6-hydroxy-hexyl-4-azophenyl-carbazol were determined. The second-order hyperpolarizability [Formula: see text] of the experiment result was found to be [Formula: see text][Formula: see text]esu. We have also calculated the second-order hyperpolarizability based on the sum-over-states (SOS) method. The theoretical value was in accord with the experiment result. The result showed that the N-6-hydroxy-hexyl-4-azophenyl-carbazol was one of the promising third-order nonlinear optical materials.
