Supramolecular Co-assembly of the Ti8L12Cube with [Ti(DMF)6] Species and Ti12-Oxo Cluster

Titanium-based coordination cages are fascinating in the field of supramolecular and photophysical chemistry. Herein, we address the unprecedented supramolecular co-assembly arrangement of a cubic Ti8L12cage with [Ti(DMF)6] species and Ti12-oxo cluster, contributing to the cocrystals of {Ti8L12+ Ti(DMF)6} (PTC-116) and {Ti8L12+ Ti12-oxo} (PTC-117). The ESI-MS and 1H NMR measurements reveal their stability in solution. The photophysical properties of these supramolecular complexes in solution, including light absorption and photoluminescent behaviors, were further investigated.
