Abstract
A novel chalcone derivative 4-{(1E,3Z)-3-(4-bromo phenyl]-3-[2-(2,4-dinitrophenyl) hydrazinylidene] prop-1-en-1-yl} phenol [BPDP] has been synthesized and structurally characterized by NMR and FTIR studies. The third order non-linear optical properties of the BPDP have been studied using single beam Z scan technique with a nanosecond-pulsed Nd: YAG laser source at 532 nm. The coefficient of non linear refraction () of the compound is found to be negative as revealed by the signature of closed aperture data. The results obtained under open aperture configuration indicate that the material exhibits reverse saturation absorption. The magnitude of real part of third-order optical susceptibility ((3) ) and of molecular second order hyperpolarizability (h) are found to be –3.5×10-20 m2V-2 and –5.9×10-48 m5V-2, respectively. The thermo gravimetric analysis shows that the material possesses a very good thermal stability up to 203°C.
