摘要
利用1,3-偶极环加成反应,在无水无氧条件下,以富勒烯C60、肌氨酸和苯甲醛为原料合成了N-甲基-2-苯基-3,4-富勒烯基吡咯烷。首次采用表面活性剂十六烷基三甲溴化铵(CTAB)协助自组装的方法制备出该C60衍生物的微米树叶状结构。结果表明:该衍生物晶体形貌和结构受溶剂种类、溶液浓度、醇与溶剂体积比、表面活性剂的影响,当以甲苯为溶剂,溶液浓度为0.75mg/mL,以5mmol/L CTAB为表面活性剂(乙醇作为溶剂),乙醇与甲苯体积比为3:1时,其晶态形貌为规则的微米树叶状结构,并对该晶态形貌进行了扫描电子显微镜(SEM)、热重分析(TG)和荧光光谱(PL)表征。
Abstract
N-methyl-2-phenyl-3,4-fulleropyrrolidine was synthesized by [60] fullerene,methyl glycosine and benzaldehyde through 1,3-dipolar cycloaddition reaction under anhydrous oxygen free condition,the morphology of micro leaf was fabricated for the first time using the self-assembly method assisted by surfactant cetyl trimethyl ammonium bromide (CTAB).The experiment results showed that the morphology and crystal structure of N-methyl-2-phenyl-3,4-fulleropyrrolidine micro leaf was obtained and controlled by using different solvents,concentration,volume ratio of alcohol and solvent,and surfactant.When toluene was as solvent,the concentration was 0.75mg/mL,the surfactant CTAB concentration was 5mmol/L (alcohol as solvent),the volume ratio of alcohol and toluene was 3:1,the crystalline structure was regular micro leaf.Moreover,the crystalline structure was characterized by scanning electron microscopy (SEM),thermal gravimetric analysis (TG) and photoluminescence(PL) spectroscopy.
