| Abstract: | Two kinds of shape‐controllable and fluorescent supramolecular organic frameworks (cuboid or spheroid) are constructed hierarchically from CB[8] and tetraphenylethylene derivatives through host–guest interaction in water. These two fluorescent SOFs exhibit intriguing and varied photophysical properties, including large red‐shifts (up to 82 nm) and stimuli‐responsive behavior to competitive guest by binding with CB[8], the turn‐on fluorescence of which is applied in cellular imaging. |
