Aqueous solution of micelles prepared from novel PS-b-PNIPAM with fluorescent group CEA at the junction between two blocks displays logical responsive switches on temperature and fluorescence; at lower temperature, stretching of PNIPAM chains causes high mobility of CEA leading to formation of more excimer species; at higher temperature, shrinking of PNIPAM chains isolates the fluorescent groups between the core and shell, resulting in fewer excimer species.
由新型PS-b-PNIPAM制备的胶束水溶液，在两个嵌段之间的连接处带有荧光基团CEA，在温度和荧光方面显示出逻辑响应开关；在较低温度下，PNIPAM链的伸展导致CEA的高迁移率，从而形成更多的准分子物种；在较高温度下，PNIPAM链的收缩将荧光基团隔离在核与壳之间，导致准分子物种减少。
