Abstract:

The use of inclusion for the development of new nonlinear optical materials is reviewed and a study of the relative intensities of second harmonic generation SHG in sorbate complexes of p-nitroaniline NA and 2-methyl-p-nitroaniline MNA in molecular sieve hosts is presented. An SHG signal ten times larger than that of any previously reported organic or organometallic inclusion complex is observed. NA in ALPO-5 complexes gave a maximum SHG of 630 relative to quartz at 13 wt. NA. Pure NA has no SHG signal. With MNA in ALPO-5 13 wt. the SHG signal is equal to that of the ALPO-5 host. X-ray powder and spectroscopic techniques were used to characterize the inclusion nanocomposites. Hydrogen bonding is found to play an important role in SHG production for NA.
