Abstract
AbstractTo study the fluorescent behavior of quantitatively confined aggregation‐induced emission (AIE) molecules in a giant cavity, herein a new type of coordination‐driven cuboctahedron cage is presented, with 12 AIE molecules anchored endohedrally linked with different‐length alkyl chains. The cage with confined tetraphenylethylene molecules shows strong fluorescence in highly diluted conditions (4 × 10−7 m). The fluorescence quantum yield can be altered from 3.23% up to 81.37%, upon prolonging the length of alkyl chains to C16. The study shows a great potential application in biology mimic and fluorescent microscopes utilizing confined or isolated fluorescent methods.
