Their structures have been well characterized. The nonlinear measurements were performed by Z-scan using 532 nm, 7 ns laser pulses. Calculated values of figure of merit and ? follow the criteria for good NLO materials. These results suggest that polymers are promising materials for applications in photonics.© 2012 The Chemical Society of Japan.
