Abstract :
4-substituted benzylidene-2-pheny-5-oxazolones (5 new compounds) were synthesized by both conventional and microwave assisted synthesis and were characterized by gas chromatography-mass spectrometry (GCMS), Fourier-transform nuclear magnetic resonance (FT-NMR) spectroscopy, and Fourier-transform infrared (FT-IR) spectroscopy. The synthetic methodology of these new compounds is presented. The results of nonlinear optical study of 4-(4′-N,N-dimethyl benzylidene)-2-phenyl oxazol-5-(4H)-one by using Z-scan techniques are discussed here. The ultrafast fluorescence decay of the molecule has been explained to be due to the electron transfer from the dimethyl group to the carbonyl group.
