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.
两种形状可控的荧光超分子有机框架（长方体或球体）通过主体-客体相互作用在水中从 CB[8]和四苯乙烯衍生物构筑而成。这两种荧光 SOF 表现出有趣且多样的光物理性质，包括大的红移（高达 82nm）和对与 CB[8]结合的竞争客体的刺激响应行为，其开启荧光可用于细胞成像。
