摘要：
The influence of fluorine substitution on the aggregation-induced emission enhancement of alternating tetraphenylethene-benzothiadiazole copolymers pBTPE and pBFTPE is investigated. The presence of difluorobenzothiadiazole in pBFTPE significantly enhances the intensity of emission upon aggregation, whereas pBTPE without fluorinated substituents exhibits relatively weak aggregation-enhanced emission. Furthermore, both the TEM image and 2-D GIWAXS reveal a denser packing for pBFTPE. The fluorine atoms on the polymer backbone may promote more pronounced inter-polymer interactions, improving molecular packing and resulting in a conformational difference. It may dictate the nature of aggregation between polymers and the resulting photophysical behavior.
