Abstract

The metallosupramolecular Ti-based M4L4 cage of [Ti4O2L4Cl8] (L = 4-acetamidobenzoic acid) is synthesized via the one-pot solvothermal reaction of 4-aminobenzoic acid, acetic acid and TiCl4. The Ti(IV) ion functions as a Lewis acid catalyst for acylation condensation, and then coordinates with the resultant 4-acetamidobenzoic acid to afford Ti-based cage formation in a cascade fashion.
