  • Synthesizing topologically complex interwoven molecules with high yield remains challenging due to structural preorganization demands. Here face-bridging ligands on metal–organic cage frameworks are shown to enable high-yield synthesis of knotted cages that mechanically trap guests inside, enhancing guest retention and structural robustness.

  • Synthetic nanocages that can adapt the size and shape of their cavity in response to a given guest have potential applications in various areas, including chemical purification. Now a flexible, pseudo-cubic metal–organic cage has been developed that is able to dynamically expand its cavity from 46% to 154% of its initial volume by flipping its cage faces.

  • Vibrational circular dichroism (VCD) spectroscopy can be useful for determining the absolute configuration of chiral molecules, as long as the signal intensities are high enough. Here, the authors establish the absolute configurations of two large chiral porphyrin cages and, notably, discover that host-guest binding enhances their VCD intensities.
