摘要

为了定量研究巨腔中受限聚集诱导发射(AIE)分子的荧光行为，本文提出了一种新型配位驱动的立方体笼，其中12个AIE分子通过不同长度的烷基链锚定在腔内。四苯基乙烯分子笼在高度稀释条件下(4 × 10−7 m)显示出较强的荧光，当烷基链长度增加到C16时，荧光量子产率从3.23%增加到81.37%。该研究显示了其在生物模拟和荧光显微镜中应用的巨大潜力。

Precisely Confined AIEgens in Giant Imidazolium–Terpyridinyl Cuboctahedra with Enhanced Fluorescence for Single Supramolecule

To 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.
