- HARD-MASK FORMING COMPOSITION, METHOD FOR MANUFACTURING ELECTRONIC COMPONENT, AND COMPOUND AND RESIN
-
A hard-mask forming composition that forms a hard mask that is used in lithography, the hard-mask forming composition including at least one of a compound represented by General Formula (sc-1) and a resin having a partial structure represented by General Formula (sc-p1). In the general formula, R11 and R12 are organic groups having 1 to 40 carbon atoms or hydrogen atoms; R13 and R14 are aromatic hydrocarbon groups having 6 to 30 carbon atoms which may have a substituent; R13 and R14 may be bonded to each other to form a structure having an aromatic heterocyclic ring, and the hydrogen atom of the phenylene group in the formula may be substituted with a substituent

- Connecting a carbonyl and a π-conjugated group through a: P-phenylene linker by (5+1) benzene ring formation
-
A benzene ring was formed to connect a carbonyl group of various methyl ketones with a π-conjugated group through a p-phenylene linker. Methyl ketones and streptocyanines were used as the C1 and C5 sources, respectively, in the (5+1) annulation, which could form donor-π-acceptor molecules.

- An Efficient Synthesis of N-(Hetero)arylcarbazoles: Palladium-Catalyzed Coupling Reaction between (Hetero)aryl Chlorides and N-Carbazolylmagnesium Chloride
-
An efficient method for the synthesis of N-(hetero)arylcarbazoles, useful compounds for functional materials, is reported. Various (hetero)aryl chlorides reacted with N-carbazolylmagnesium chloride in the presence of a palladium catalyst (0.05 to 0.2 mol%) prepared from allylpalladium(II) chloride dimer {[PdCl(allyl)]2} and di-tert-butyl(2,2-diphenyl-1-methylcyclopropan-1-yl)phosphine (cBRIDP) under mild conditions (110°C) in a short period of time (15 min to 2 h) to give N-(hetero)arylcarbazoles in high yields. The reactions of bromochlorobenzenes proceeded in favour of the bromo group to afford N-(chlorophenyl)carbazoles in a highly selective manner. Functional materials for use in organic light-emitting diodes, such as mCP, 26mcPy, CBP and TCB, were also obtained in high yields within 15 min by the reaction of (hetero)aryl polyhalides. Optimization of the reaction conditions and a postulated catalytic cycle for the reaction are also discussed.
