Synthesis and nonlinear optical characterization of new 1,3,4-oxadiazoles

Abstract

A new series of 1,3,4-oxadiazole derivatives containing 2-fluoro-4-methoxy phenyl were synthesized by refluxing mixture of acid hydrazide 3 with different aromatic carboxylic acids (a-e) in phosphorous oxychloride. These newly synthesized compounds were characterized by NMR, mass spectral, and IR spectral studies, and also by C, H, N analyses. The open-aperture z-scan experiment was employed to measure the optical nonlinearity of the samples at 532 nm, using 5 ns laser pulses. The measurements indicate that compound 4a, which contains Bromine, behaves as an optical limiter at this wavelength, with potential applications in optoelectronics.

Third order nonlinear properties in the 1,1′-Methylenedipyridinium bis[tetrachloridoaurate(III)] using Z-Scan technique

“…organic molecules [4][5][6], organic dyes [7] and fullerenes [8][9]. Recently, organometallic complexes have attracted attention as promising third-order NLO materials [10][11][12][13].…”

1-[5-(4-Tolyl)-1,3,4-oxadiazol-2-yl]methanamine

“…Among the preeminent heterocyclic compounds, oxadiazole structures have been demonstrated to be good electron-transporting (ET) materials and prominent hole blockers (HB) used in organic optoelectronic devices [1][2][3]. 1,3,4-oxadiazoles are the most widely studied class of ET materials due to their electron deficiency, high photoluminescence quantum yield, and good thermal and chemical stabilities [4][5][6][7].…”
