摘要

Nonlinear optical (NLO) organic crystals have attracted a lot of attention because of their quick response time and great optical nonlinearity. In this work, a novel organic isoniazid–pimelic acid (IPA) crystal was synthesized using the slow evaporation technique at room temperature. Structural confirmation was achieved through single-crystal and powder X-ray diffraction analyses. The presence of various functional groups and the vibrational modes were identified by FTIR and FT-Raman spectroscopy. The molecular structure was confirmed by 1H and 13C NMR analyses. Optical studies revealed a wide transparency range with a low cut-off wavelength of 372 nm, indicating the suitability of the crystal for optoelectronic applications. Photoluminescence analysis exhibited two prominent emission peaks at 397 and 488 nm. The IPA crystal exhibited a second harmonic generation efficiency of 1.67 × KDP. Mechanical stability and dielectric behaviour were evaluated using Vickers microhardness and the frequency-dependent dielectric constant and dielectric loss analyses. These combined optical, mechanical and NLO characteristics indicate that the isoniazid–pimelic acid crystal is a promising material for NLO and optoelectronic device applications.
