Structures and photophysical performances of (fluoro)salicylate stabilized polyoxo-titanium clusters

Abstract

The introduction of fluorine in salicylic acid yielded different polyoxo-titanium clusters with distinct photophysical properties.

Binding Modes of Salicylic Acids to Titanium Oxide Molecular Surfaces

“…Zhu et al. also synthesized Ti 13 (FSA) 9 and Ti 14 (SA) 8 , both of which have the same structures as the current ones. Different from both of the above reports, it has been found in our study that salicylic acids with many types of substituents can be used.…”

A Mesoporous Lead-Doped Titanium Oxide Compound with High Performance and Recyclability in I2 Uptake and Photocatalysis

“…Titanium oxide clusters (TOCs) represent a class of discrete, molecular metal oxides with the size between small molecules and nanoparticles. During the past decade, the research interest in TOCs has grown due to their atomically precise structures, their roles as molecular analogues of TiO 2 nanoparticles, and their outstanding photocatalytic activities. , Much effort has been spent on the syntheses of TOCs, and numerous TOCs and metal-doped TOCs have been reported. − We noticed that pure inorganic titanates like Na 2 TiO 3 exhibit merits like low toxicity, abundance, and low cost and have proven to be useful in sequestration of radioactive cationic ions like Cs + , Sr 2+ , and UO 2 2+ from aqueous solutions. − By contrast, TOCs are the hybrids of inorganic and organic counterparts. Hence, we envisaged that porous TOCs may be suitable adsorbents for reprocessing of neutral molecular I 2 . , However, although a few cagelike TOCs that could encapsulate guests like {Cs@Ti 12 }, {I@Ti 22 }, and {Br@Ti 15 } have been reported, their cavities are still very small.…”

Synthesis, Crystal Structures, and Photochemical Properties of a Family of Heterometallic Titanium Oxo Clusters

“…Titanium oxide clusters (TOCs) have attracted extensive research interest in the past decade as structural and reaction models of TiO 2 nanoparticles. − Their precise structural information provides the basis for accurate studies of the structure–property relationship and photocatalytic mechanism in these systems . On the basis of the mentioned heterometal-doped TiO 2 material, chemists’ started to work on the preparation and structural identification of heterometallic titanium oxo cluster complexes. − It is also very attractive that the band gap of TOCs can be effectively adjusted by doping with transition-metal ions. − Currently, most of the studies on the heterometallic TOCs focused on their structures, − but very few studies have been conducted on their photoelectric properties and their application in photocatalytic H 2 production.…”
