Tetraarylmethanes are an important class of molecules that contain four aryl groups bonded to a central carbon atom. The shape/three-dimensionality of these molecules makes them suitable for organic light-emitting diodes (OLEDs), organic solar cells, hydrogen storage, and even drug-delivery. Despite their importance, there are only a few methods available for their preparation. Herein, we report a simple procedure for the preparation of tetraarylmethanes that involves a bismuth-catalyzed Friedel-Crafts cyclization followed by a desulfurization reaction mediated by Raney nickel.

Paragraph 0029; 0034; 0036-0037, (2018/03/23)
The present invention relates to a novel compound which due to having little difference between a singlet energy state and a triplet energy state, exhibits a thermally activated delayed fluorescence by reverse intersystem crossing when heat is applied, that generates the singlet energy state from the triplet energy state; and to an organic light-emitting device which applies the same to a dopant of an organic light-emitting layer. Specifically, the present invention relates to a compound represented by chemical formula 1; and to an organic light-emitting device which applies the same to a dopant of an organic light-emitting layer, wherein in the chemical formula 1, R_1 and R_2 may be identical or different from each other, and are a pyridoindole group, a phenyl group, a carbazole group, a 9,9-dimethyl-9,10-dihydroacridine group, a 10H-phenothiazine group, or 10H-phenoxazine group, and R_3 is a methyl or phenyl group.COPYRIGHT KIPO 2017
Synthesis and characterization of ortho-thio-functionalized triarylmethyl palladium complexes

A series of triarylmethyl palladium complexes with ortho coordination sites were synthesized. Thereby, the palladium atom exhibits various inter- and intramolecular binding modes towards the organic ligand. Further, the first crystallographically proven, exclusively σ-coordinated triarylmethyl palladium complexes, stabilized by ortho-thio-substituents, were discovered. The NMR spectra of the palladium complexes indicate temperature-dependent dynamic behavior.

Reactions of 9-phenylthioxanthene 10-oxide (1) with a variety of Grignard reagents afforded 9-substituted 9-phenylthioxanthenes (2). Similarly, organolithiums reacted with the sulfoxide 1 to give the corresponding thioxanthenes 2. The structures of 9-aryl
