Co-crystal Growth and Characterizations of Diisopropylammonium Hydrogen Phthalate

Abstract

Slow evaporation solution growth approach has been utilized to synthesize the single co-crystal of diisopropylammonium hydrogen phthalate at room temperature. Its structural attributes owing to the refinement of its cell parameters have been successfully confirmed using Debye – Scherrer method. Ultraviolet-visible spectroscopy has further revealed the optical behaviour of the aforesaid crystal having a 301 nm cut-off with a broad direct optical energy band of 4.09 eV. Its vibrational assignments have been determined using Fourier transform infrared spectral study. Photoluminescence spectroscopy has highlighted the violet emission from the crystal when stimulated by 300 nm excitation wavelength. Vickers micro hardness technique has as certained the mechanical strength of the grown crystal along with the work-hardening coefficient thereby claiming its normal ISE behaviour to the external load. Conclusively, this work has featured the prominence of diisopropylammonium hydrogen phthalate co-crystal for optical applications.
