Title: TETRAPHENYLNAPHTHALOCYANINE COMPOUND, METHOD FOR PRODUCING SAME, AND USE OF SAME
Abstract:
[Problem] To provide: a novel naphthalocyanine compound which has intense absorption in a near-infrared region and extremely small absorption of a visible light region, and has high durability and good solubility in organic solvents and resins; a method for producing the naphthalocyanine compound; an intermediate; and the use of the naphthalocyanine compound. [Solution] A tetraphenylnaphthalocyanine compound represented by general formula (1); a method for producing the tetraphenylnaphthalocyanine compound; and an intermediate. [In formula (1), M represents two hydrogen atoms, a bivalent metal, or a derivative of a trivalent or tetravalent metal; R1 to R4 independently represent a hydrogen atom, a halogen atom or an alkyl group; and A represents a group represented by formula (B).] [In formula (B), X1 and X2 independently represent a hydrogen atom, a fluorine atom or an alkyl group substituted by a fluorine atom, wherein a case in which each of X1 and X2 represents a hydrogen atom is excluded.]
