Two novel compounds, named [Ti₂Na₄(BTC4A)₂(μ₆-O²⁻)(CH₃O⁻)₂·2H₂O·2DMA] (1) and [Ti₄(BTC4A)(OH⁻)₄(EtO⁻)₆(ⁱPrO⁻)₂] (2) (H₄BTC4A= p-tert-Butylthiacalix [4] arene), have been synthesized and characterized. Single crystal diffraction shows that compound 1 features a dumbbell-like molecule based on an octahedral Ti₂Na₄ core and two BTC4A⁴⁻ ligands with cone conformation. Compound 2 is composed of a bi-titanium(IV) unit and a BTC4A⁴⁻ ligand with 1,2-alternate conformation. The estimated optical bandgaps of compounds 1 and 2 are 2.87 and 1.97 eV, respectively, which are smaller than that of TiO₂. Moreover, compounds 1 and 2 display much higher and more efficient photocatalytic degradation abilities for methylene blue than TiO₂ under visible light irradiation.
