Two Novel Titanium(IV)-Based Compounds Supported by Thiacalix[4]arene: Syntheses, Structures and Photocatalytic Properties
Abstract Two novel compounds, named [$ Ti_{2} $$ Na_{4} $(BTC4A)2($ μ_{6} $-$ O^{2−} $)($ CH_{3} $$ O^{−} $)2·$ 2H_{2} $O·2DMA] (1) and [$ Ti_{4} $(BTC4A)($ OH^{−} $)4($ EtO^{−} $)6(i$ PrO^{−} $)2] (2) ($ H_{4} $BTC4A= 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 $ Ti_{2} $$ Na_{4} $ core and two $ BTC4A^{4−} $ ligands with cone conformation. Compound 2 is composed of a bi-titanium(IV) unit and a $ BTC4A^{4−} $ 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 $ TiO_{2} $. Moreover, compounds 1 and 2 display much higher and more efficient photocatalytic degradation abilities for methylene blue than $ TiO_{2} $ under visible light irradiation..
