The complex of o-phenylenediamine (o-PDA) and benzoin (BN) was synthesized adopting solid state reaction by mixing of their melt together followed by chilling. The phase diagram study shows the formation of a complex in 1:1 molar ratio with congruent melting point and two eutectics lying on either side of complex. The formation of complex was confirmed using the FTIR, NMR, mass spectroscopy, powder XRD and DSC studies. The optical properties of the parent component, their complex and few other compositions nearby the complex were studied using absorption and laser luminescence techniques. The significantly higher green/yellow emission was noted with newly synthesized complex as compared to that of their parents as well as other compositions of o- PDA and BN.
通过将邻苯二胺(o-PDA)和安息香(BN)的熔体混合在一起并冷却,采用固态反应合成了邻苯二胺(o-PDA)和安息香(BN)的复合物。相图研究表明,以 1:1 的摩尔比形成的复合物具有相同的熔点,复合物的两侧有两个共晶。傅立叶变换红外光谱、核磁共振、质谱、粉末 XRD 和 DSC 研究证实了复合物的形成。利用吸收和激光发光技术研究了母体成分、它们的复合物以及复合物附近一些其他成分的光学特性。与母体以及邻苯二甲酸二异戊酯和 BN 的其他成分相比,新合成的复合物的绿色/黄色发射率明显更高。
