摘要

A new kind of emissive small-molecular organic cage has been developed via the combination of coupling and condensation reactions, which shows outstanding solubility, structural stability and potential spatial isomeric chirality. Interestingly, through the introduction of proper donor and acceptor units, this emissive organic cage is the first among organic cages to exhibit red aggregation-induced delayed fluorescence with photoluminescence emission at 603 nm. The finding not only expands the types of emissive small-molecular organic cages, but also represents an important step for further development of red delayed fluorescence materials with good solubility and aggregation-induced emission feature.
