Measurement on the third-order optical nonlinearity of C70 and its poly-aminonitrile derivative by using the femtosecond optical Kerr effect

Bis(tetrabutylammonium)- Hg(dmit) 2 was synthesized and its sample solution's optical Kerr Effect (OKE) signal was measured by the femtosecond optical Kerr gate technique. With the concentration of 9.27 × 10-4 M, the sample solution's third-order optical susceptibility was obtained to be 2.53 × 10-14 esu by using the CS2 OKE signal as reference signal measured under identical conditions. The second-order hyperpolarizability for the bis(tetrabutylammonium)- Hg(dmit) 2 molecular was estimated to be 1.7 × 10-32 esu. Its response time was about 226 fs, which is believed to be the contribution from the delocalized electrons.

One Step

ABSTRACTSilver phenylacetylide prepared by one-step process was characterized as a linear coordinated polymeric compound by matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectroscopy. Its prominent third-order optical nonlinearity was detected by heterodyned ultrafast optical Kerr effect (OHD-OKE) measurement. The second-order hyperpolarizability was enhanced by 2 orders of magnitude by means of incorporation of proper electron-pushing groups. The structure status was further investigated by quantum chemical calculation and molecular modeling.

The Relationship

The femtosecond optical heterodyne detected optical Kerr effect is described in detail. The real and the imaginary parts of complex third-order optical nonlinearity can be effectively separated and their values and signs can be determined. Using this method, we thoroughly investigated the substitution effect by adding different side-groups on the –(–C=N–)– conjugated system, a new class of nonlinear optical material. We discussed the improvement in their third-order susceptibilities. And we found the value of second-order hyperpolarizability depends on the polymerization degree, but the relationship is different for different substituted polymers.
