General Description

2-Bromo-10-thiaxanthenone is a chemical compound that primarily belongs to the family of xanthenes, which are polycyclic aromatic compounds containing a xanthene moiety. The systematic name of the compound is 2-bromo-10H-thioxanthen-9-one. It has a role as an environmental contaminant and a genotoxicant. It is generally used for research purposes and its molecular formula is ?C14H9BrOS. Like many chemical compounds, it needs to be handled with care as it may pose health hazards. However, specific properties including its melting and boiling points, or details about its toxicity, are not readily available and it is not widely discussed in scientific literature.

A highly efficient purely organic room-temperature phosphorescence film based on a selenium-containing emitter for sensitive oxygen detection

Developing purely organic room-temperature phosphorescence (RTP) materials with high phosphorescence efficiency in film states is important for their applications but remains a great challenge. Herein, a donor-acceptor type RTP molecule (SeX-CzPh) with 9H-selenoxanthen-9-one and 9-phenyl-9H-carbazole as the acceptor and donor units, respectively, is designed and synthesized.SeX-CzPhshows a high phosphorescence quantum yield of 44.3% in a doped polystyrene film at room temperature, which is 4-fold higher than that of its analogueTX-CzPhwith 9H-thioxanthene-9-one as the acceptor unit. The heavy selenium atom plays a key role in achieving high phosphorescence quantum yields, owing to the effective ISC process through strong spin-orbit coupling. Moreover, theSeX-CzPh-based oxygen film sensor exhibits a wide detection range (0-2.1 × 105ppm), a highKSV(1.27 × 10?4ppm?1) and a low detection limit (4.9 ppm). This work demonstrates that 9H-selenoxanthen-9-one is a promising building block for the rational design of highly efficient purely organic RTP materials.

Evaluating brominated thioxanthones as organo-photocatalysts

Bromination of the widely used triplet sensitizer thioxanthone extends the absorption spectrum into the visible range with only minor loss of lowest triplet state energy (3?kcal/mol for di-bromination). Because of bromine substitution, a slight increase in triplet quantum yield was observed. The di-brominated derivative was effective as organo-photocatalyst in performing [2?+?2] cross-photocycloaddition of acrylimide-based compounds under visible light irradiation.

Formation and Disproportionation of Xanthenols to Xanthenes and Xanthones and Their Use in Synthesis

A facile and versatile strategy employing TiCl4-mediated cyclization followed by a Cannizzaro reaction has been developed for the synthesis of various xanthene derivatives. The reaction proceeded smoothly to afford both xanthenes/xanthones or their sulfur derivatives and tolerated a wide range of electronically diverse substrates. Using this methodology, pranoprofen was synthesized in three steps in 59% overall yield from commercially available starting materials.
