Growth of 2-amino-5-chlorobenzophenone single crystal by Microtube Czochralski method and its characterization

Organic single crystals of 2-amino-5-chlorobenzophenone (2A5CB) were grown by Microtube Czochralski method using Microtube as a seed. The grown crystals were characterized by single crystal and powder X-ray diffraction. The functional groups of the grown crystal were found using Fourier transform infrared spectroscopy. The cutoff wavelength of 2A5CB has been identified using UV–vis–NIR studies. Thermogravimetric/differential thermal analysis (TG/DTA) has been carried out to find the thermal behaviour. 2A5CB was found to be thermally stable up to 125∘C. Powder second harmonic generation (SHG) was investigated to explore its nonlinear optical (NLO) properties. The mechanical stability of 2A5CB is studied by using Vickers hardness testing.
