A dibenzopyrromethene boron chelate compound is represented by the following formula (1): 

Dibenzopyrromethene boron chelate compound, near-infrared light absorbing material, thin film and organic electronics device

A compound is represented by the formula, Rto Rare each a hydrogen atom, aliphatic hydrocarbon group, aromatic group, heterocyclic group, a halogen atom, or the like. One of Xto Xis a sulfur atom, and the remaining two are carbon atoms having one R. One of Xto Xis a sulfur atom, and the other two are carbon atoms having one R. Ris a hydrogen atom, aliphatic hydrocarbon group, aromatic group, heterocyclic group, a halogen atom, or the like. When Xand Xare each RC, Xand Xare each RC, Xand Xare each RC, or Xand Xare each RC, the adjacent Rs may be bounded to each other to form a cyclic structure.

Dibenzopyrromethene boron chelate compound, near-infrared light-absorbing material, thin-film, and organic electronic device

[Problem] To provide: a novel compound which has high mobility and on/off ratio and is useful for organic electronic devices; and a method for producing the compound. [Solution] A condensed polycyclic aromatic compound which is represented by general formula (1). (In the formula, A represents a 1,5-dihydronaphthalene ring or a 2,6-dihydronaphthalene ring; each of R, R, Rand Rindependently represents a hydrogen atom, a halogen atom, a substituted or unsubstituted aliphatic hydrocarbon group, a substituted or unsubstituted alicyclic hydrocarbon group, a substituted or unsubstituted aromatic hydrocarbon group, a substituted or unsubstituted hydrocarbon oxy group, a substituted or unsubstituted ester group, a substituted or unsubstituted acyl group, or a substituted or unsubstituted cyano group; and each of Xand Xindependently represents an oxygen atom, a sulfur atom or a selenium atom.) 

Condensed polycyclic aromatic compound and use thereof

The present invention provides a fused aromatic compound represented by general formula (1) or general formula (2): wherein Rto Reach independently represent an atom or a functional group selected from the group consisting of a hydrogen atom, a halogen atom, a hydrocarbon oxy group, an aromatic hydrocarbon group, an aliphatic hydrocarbon group, an alicyclic hydrocarbon group, an ester group, an acyl group, a cyano group, and a substituted silyl group, Xto Xeach independently represent a cyano group, an ester group, or an acyl group, and Yto Yeach independently represent an oxygen atom, a sulfur atom, or a selenium atom.

Fused polycyclic aromatic compounds, organic semiconductor material and thin film including the same, and method for producing an organic semiconductor device

A method for producing a heterocyclic compound represented by general formula (2) from a heterocyclic compound represented by general formula (1) (in the formulae, X1 represents a halogen atom; each of Y1 and Y2 independently represents an oxygen atom, sulfur atom, or selenium atom; each of R1 and R2 independently represents a substituent; m and n respectively represent the number of substituents R1 and R2, each of m and n representing an integer of 0-4; and when m and n are 2 or higher, R1 and R2 may be the same or different and may bond to each other to form an optionally substituted ring).
