キーワード：Optical trapping, Aggregation-induced emission enhancement

Optical trapping has been utilized as a powerful method for the manipulation of nano/micrometer-sized objects. Our group has extended this optical trapping method to generate assembling and crystallization of various molecules. Most recently, we succeeded in demonstrating aggregation-induced emission enhancement (AIEE) of a tetraphenylethene (TPE) derivative using this method and controlling its AIEE phenomenon arbitrarily by tuning laser power. In this work, we extend the method to a polymer appended by TPE and investigate the temporal change in fluorescence upon its aggregation.
