Growth and characterization of organic material 2-methylamino-5-chlorobenzophenone single crystal by modified vertical Bridgman technique.

The organic material 2-methylamino-5-chlorobenzophenone single crystal has been grown by modified vertical Bridgman technique using the single wall ampoule with nano translation. The grown crystal was confirmed by single crystal and powder X-ray diffraction analyses. Fourier transform infrared analysis was used to identify the functional groups present in the grown crystal. High resolution X-ray diffraction studies show the crystalline perfection of the grown crystal. The optical property of the grown crystal was analyzed by UV-vis-NIR and photoluminescence spectral studies. The thermal behavior of the grown crystal was analyzed by thermogravimetric and differential thermal analyses. The dielectric measurements of the grown crystal were carried out with different frequencies and temperatures and the results indicate an increase in dielectric and conductivity parameters with the increase of temperature at all frequencies. The microhardness measurements were performed to analyze the mechanical property of the grown crystal.
