National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

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)
