- Abstract
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.
