Synthesis,growth and spectroscopic investigation of an organic molecular charge transfer crystal: 8-Hydroxy quinolinium 4-nitrobenzoate 4-nitrobenzoic acid

摘要

An organic intermolecular charge transfer complex salt of 8-Hydroxy quinolinium 4-nitrobenzoate 4-nitrobenzoic acid (OPNB) has been synthesized.Single crystals of OPNB were grown by slow solvent evaporation solution growth technique at room temperature.The 1H and 13C NMR spectra were recorded to confirm the molecular structure of the complex salt.The crystal structure of OPNB has been determined by single crystal XRD analysis and it belongs to triclinic crystal system with space group P-1.Fourier transform infrared (FT-IR) spectral study has been carried out to identify the various functional groups present.The UV-Vis-NIR transmittance spectrum was recorded in the range 200-2500 nm,to find the suitability of the single crystal for various optical applications.The thermal stability of the crystal was investigated using thermogravimetric (TG) and differential thermal analyses (DTA).
