Inclusion Tuning of Nonlinear Optical Materials: SHG (Second Harmonic Generation) of Organic Guests in Molecular Sieve Hosts

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.
