Organic piperazine p-nitrophenol (PPN) single crystal growth and characterization

Abstract

The monitored conventional solution growth technique was used to develop organic piperazine p-nitrophenol (PPN) single crystals. The crystal system and lattice parameters of PPN were confirmed using powder single crystal X-ray analysis. FTIR spectroscopy used to investigate functional groups of PPN. A UV–vis-NIR analysis was performed to examine the cut-off wavelength and the optical operating window. The bandgap of the material was measured. Thermogravimetric and Differential Thermal Analysis measurements was used to determine the thermal characteristics of PPN crystal. At room temperature, the Vickers microhardness test was used to determine mechanical stability. The results of hardness were examined using Meyer's law. The Kurtz and Perry powder method is used to measures the Second Harmonic Generation of PPN crystals.
