Copper(II)-catalyzed C-H/C-H coupling of dipolar 2-H-benzothiazoles end-capped with triphenylamine moieties affords highly fluorescent 2,2′-bibenzothiazoles with quadrupolar (D-π-A-π-D) architecture displaying large two-photon absorption (TPA) cross sections (543-1252 GM) in the near-infrared region. The notably higher TPA performance as compared to quadrupolar π-systems with a widely used 2,2′-bipyridine core, along with the ease of the synthesis and chelating N^N ability, makes the title biheteroaryl platform an attractive building block for a large scope of functional dyes exploiting nonlinear optical phenomena.

A practical and switchable method for the synthesis of aryl sulfones and sulfoxides via sulfide oxidation was developed. The chemoselectivities of products were simply controlled by reaction temperature using O2/air as the terminal oxidant and oxygen source. The broad substrate scope, easy realization of gram-scale production, and the simplification of a sulfide oxidation system render the strategy attractive and valuable.

Paragraph 0198, (2018/03/23)
PROBLEM TO BE SOLVED: To provide a salt to be used for a resist composition that allows production of a resist pattern with good line edge roughness.SOLUTION: The salt is expressed by the formula (I). In the formula, Qand Qrepresent a fluorine atom or a perfluoroalkyl group having 1 to 6 carbon atoms; Lrepresents a divalent saturated hydrocarbon group having 1 to 20 carbon atoms; Yrepresents a group expressed by the formula (Iy); R' represents a hydrogen atom, an alkyl group having 1 to 6 carbon atoms which may have a fluorine atom, or a hydroxyl group; X' represents a single bond, -O-, *-CO-O-, or the like; Ar represents a phenylene group; Rand Rrepresent an aliphatic hydrocarbon group having 1 to 10 carbon atoms which may have a substituent, an alicyclic hydrocarbon group having 4 to 36 carbon atoms which may have a substituent, an aromatic hydrocarbon group having 6 to 36 carbon atoms which may have a substituent, or a heterocyclic group having 6 to 36 carbon atoms which may have a substituent; and Lrepresents a divalent hydrocarbon group having 1 to 36 carbon atoms which may have a substituent.
