Abstract
Functional dicyclophanes with various substituents (e.g., NO2, Br, OCH3 and OH) were synthesized via one-pot SN2 reaction. Dicyclophanes can form nanospheres via the head-to-tail self-assembly between the cavities and the TPE units to exhibit aggregation-induced emission (AIE) in aqueous solution. These AIE-active nanospheres with cationic feature exhibited selective recognition with fluorescence response for anionic ATP via electrostatic interactions and hydrophobic effects in water.
