The semicarbazone of p-anisaldehyde (SPAS) is a novel organic nonlinear optical material. The SPAS has been synthesized and the solubility studies were carried out in the temperature range 30-60 °C. Single crystals of SPAS have been grown following the slow evaporation technique and the unit cell parameters have been evaluated by single crystal X-ray diffraction technique. The UV-Visible, FT-IR and 1HNMR spectra have been recorded to characterize the grown crystal. The thermogravimetric and differential thermal analysis of the grown crystal revealed that there is no phase transformation in SPAS, and its thermal stability was found to be good. The dielectric measurement was made as a function of frequency (50 Hz - 5 MHz). The second harmonic generation in the sample was confirmed by the Kurtz powder technique.Keywords

Four copolyesters were synthesized from 3,3-(1,4-phenylene)bis(1-(4-hydroxyphenyl)prop-2-en-1-one (THAP) and 3,3-(1,4-phenylene)bis(1-(4-hydroxy-3-methoxyphenyl)prop-2-en-1-one (TMAP) by phase transfer catalyzed polycondensation with adipoyl chloride and sebacoyl chloride and a common diol-I 1,5-dihydroxynaphthalene. These copolyesters were characterized by solubility data and viscosity values. The microstructure of the repeating unit was confirmed by IR, 1H NMR and 13C NMR. These copolyesters displayed potential bactericidal activity against pathogenic bacteria.Keywords
