Functional molecular
capsules have attracted a lot of attention in recent years because
of their potential applications as chemosensors, catalysis, drug carriers,
and so on. We report here the coordination-directed self-assembly
of a fluorescent-lantern-type molecular capsule from four tetraphenylethylene-based
ditopic ligands and two square-planar palladium(II) ions. The capsule
has been thoroughly characterized by UV–vis, 1D/2D NMR, electrospray
ionization time-of-flight mass spectrometry, and single-crystal X-ray
diffraction studies. The aggregation-induced emission performance
of the capsule has been studied by tuning the ratio of mixed solvents.
Moreover, with an open cavity, the fluorescence of the capsule also
displays anion sensitivity, with the best turn-on responsiveness observed
for HCO<sub>3</sub><sup>–</sup>, demonstrating for the first
time an encapsulation-induced emission property.
