Abstract : 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 have a maximum SHG of 630 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 diffraction was used to characterize the inclusion nanocomposites. The ability to switch on and enhance SHG in NA and switch off SHG in MNA is ascribed to sorbate-host and sorbate-sorbate alignment interactions. Anilines, Nitroradicals. (MJM)
