摘要：制备了一种新型的磺酸功能化离子液体,并以离子液体[Bmim]Cl作溶剂,以所合成的新型的磺酸功能化离子液体作催化剂,催化水解纤维素使其转化为荧光碳点。实验结果表明:制备的碳点对反应时间有着良好的荧光可调性;随着反应时间的延长,所形成碳点的最大激发波长和发射波长均出现规律性红移现象。
A novel SO3H-functionalized ionic liquid based on 2-Phenyl-2-imidazoline was synthesized. The conversion of cellulose into carbon dots in [Bmim]Cl catalyzed by SO3H-functionalized ionic liquid was investigated, and the obtained carbon dots showed favorable tunable property of fluorescence. It was found that the fluorescent emission wavelength showed a red-shift with increasing reaction time.
