High-valence Ti(IV)-based metallocalixarene coordination cages that are linked by oriented ancillary ligands are unknown so far. Herein, the first family of tunable calixarene-based coordination cages of Ti(IV) with a framework formula [Ti(OPr)(TBC[4])L] have been assembled from six {Ti(OPr)(TBC[4])} nodes and six pyridinedicarboxylic ligands. Furthermore, the {Ti12L6} cage showed strong photocatalytic H evolution activity, and DFT studies were performed to explore its electronic structure.
