New organic material has been synthesized and single crystals were grown from aqueous solution. Single crystals of 4-methylpyridinium picrate have been grown by slow evaporation technique acetone as a solvent at room temperature. Single crystal X-ray diffraction study on grown crystals shows that it belongs to monoclinic system. Fourier transform infrared (FTIR) spectroscopic study was performed for the identification of different modes of functional groups present in the compound. The thermal stability of the compound has been determined by TG-DTA curves. The result shows that the material starts decomposing at 171.50 °C. The UV-visible transmission spectrum has been recorded in the range 190-900 nm. The photoconductivity study confirms the negative photoconductive nature of the sample. The dielectric measurement of the compound has been analyzed using dielectric analysis. Laser damage threshold value for the crystal was measured.
我们合成了新的有机材料,并从水溶液中生长出了单晶体。4- 甲基吡啶鎓吡啶盐的单晶体是以丙酮为溶剂,在室温下通过缓慢蒸发技术生长出来的。对生长出的晶体进行的单晶 X 射线衍射研究表明,它属于单斜体系。傅立叶变换红外(FTIR)光谱研究用于确定化合物中存在的官能团的不同模式。化合物的热稳定性是通过 TG-DTA 曲线测定的。结果表明,该材料在 171.50 °C 时开始分解。在 190-900 纳米范围内记录了紫外-可见透射光谱。光电导研究证实了样品的负光电导性质。利用介电分析法对化合物的介电测量进行了分析。测量了晶体的激光损伤阈值。
