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

摘要

A compound is represented by the formula, R₁ to R₈ are each a hydrogen atom, aliphatic hydrocarbon group, aromatic group, heterocyclic group, a halogen atom, or the like. One of X₁ to X₃ is a sulfur atom, and the remaining two are carbon atoms having one R₀. One of X₄ to X₆ is a sulfur atom, and the other two are carbon atoms having one R₀. R₀ is a hydrogen atom, aliphatic hydrocarbon group, aromatic group, heterocyclic group, a halogen atom, or the like. When X₁ and X₂ are each R₀C, X₂ and X₃ are each R₀C, X₄ and X₅ are each R₀C, or X₅ and X₆ are each R₀C, the adjacent R₀s may be bounded to each other to form a cyclic structure.
