Abstract:
1. An ink composition comprising phthalocyanine nanowires which contain phthalocyanine and a phthalocyanine derivative and an organic solvent as essential components, the ink composition being characterized in that: 1) the phthalocyanine is copper phthalocyanine, zinc phthalocyanine, or iron phthalocyanine; 2) the phthalocyanine derivative is represented by general formula (1), or (3) described below; and 3) the minor diameter of the phthalocyanine nanowires is 100 nm or less, and the ratio (length/minor diameter) of the length to the minor diameter is 10 or more; wherein in the formulae (1) and (2), X is selected from the group consisting of a copper atom, a zinc atom, a cobalt atom, a nickel atom, a tin atom, a lead atom, a magnesium atom, a silicon atom, and an iron atom, and Y when Y when Y wherein in the formula (3), X is selected from the group consisting of a copper atom, a zinc atom, a cobalt atom, a nickel atom, a tin atom, a lead atom, a magnesium atom, a silicon atom, and an iron atom, Z is a group represented by a formula (a) or (b) described below, a, b, c, and d each independently represent an integer of 0 to 2 but at least one of a, b, c, and d is 1; wherein n is an integer of 4 to 100, each Q is independently a hydrogen atom or a methyl group, and Q′ is a noncyclic hydrocarbon group having 1 to 30 carbon atoms wherein m is an integer of 1 to 20, and R and R′ are each independently an alkyl group having 1 to 20 carbon atoms.
