摘　　要：室温磷光材料在传感器、成像、防伪等方面的应用而受到关注。本文以均苯三甲酸和胞嘧啶为原料,通过水热法合成出一例具有室温磷光性质的有机共晶。X射线单晶衍射表明,均苯三甲酸与胞嘧啶之间发生了质子转移,晶体结构中存在着丰富的氢键作用。利用X射线粉末衍射、热重分析、光致发光等手段测试了有机共晶的物理性能。结果表明,有机共晶具有出色的热稳定性,可达200℃,并表现出绿色发光的室温磷光,磷光寿命达到0.2s。Room temperature phosphorescent materials have attracted much attention for their applications in sensors,imaging,anti-counterfeiting and so on.An organic co-crystal with room temperature phosphorescence was synthesized by hydrothermal method with trimesic acid and cytosine as raw materials.X-ray single crystal diffraction showed that proton transfer occurred between trimesic acid and cytosine,and there were abundant hydrogen bonds interactions in the crystal structure.The physical properties of organic co-crystal were tested by X-ray powder diffraction,thermogravimetric analysis and photoluminescence.The results show that the organic co-crystal has excellent thermal stability up to 200℃,and exhibits green room temperature phosphorescence,and the phosphorescence life reaches 0.2 seconds.
