Fluorescence responsive conjugated poly(tetraphenylethene) and its morphological transition from micelle to vesicle†
Abstract
A crown ether-functionalized poly(tetraphenylethene) (AP-TPE) is synthesized and the rotation of the TPE group is successfully restricted via the complexation of crown ether and organic ammonium salts, leading to a stepwise enhanced fluorescence accompanied by a morphological transition from micellar to vesicular.
