Abstract:
以香豆素为光敏感基元,通过多步反应制备了三臂ATRP引发剂C-Br3,然后以CuBr/PMDETA为催化体系、甲基丙烯酸2-(二甲氨基)乙酯(DMAEMA)为单体,ATRP聚合法制备了三臂星形聚合物C-(PDMAEMA)3.用傅里叶变换红外光谱仪(FTIR)、紫外-可见光分光光度计(UV-Vis)和核磁共振仪(1H-NMR)等对C-Br3及聚合物进行了结构表征.研究表明,该三臂星形聚合物可在水中直接形成胶束,且该聚合物可在365和254nm交替紫外光照下发生可逆光二聚反应.纳米粒度跟踪显示,光照前其胶束粒径为(87.7±27.8)nm、呈高斯分布;而在365和254nm光反应后,聚合物胶束粒径大小与分布仅发生微弱变化.这可能是因为在光二聚反应前后,聚合物的双亲结构变化微弱所致.
