Abstract

The thiol group-containing colored compound includes a chromophore having absorption in a visible light region, a thiol group, and a spacer provided between the chromophore and the thiol group. The spacer is a chain alkylene group having 2 to 30 carbon atoms, a cyclic alkylene group having 3 to 30 carbon atoms, or a derivative of either alkylene group in which the number of carbon atoms in an additional structure of the alkylene group is equal to or less than the number of carbon atoms in the alkylene group.

First claim

1 . A thiol group-containing colored compound comprising:
a chromophore having absorption in a visible light region, a thiol group, and a spacer provided between the chromophore and the thiol group, wherein the spacer is a chain alkylene group having 2 to 30 carbon atoms, a cyclic alkylene group having 3 to 30 carbon atoms, or a derivative of either alkylene group in which the number of carbon atoms in an additional structure of the alkylene group is equal to or less than the number of carbon atoms in the alkylene group.

2 . The thiol group-containing colored compound of claim 1 , wherein the compound is represented by general formula (I):
R—W—SH  (1)
where R is a chromophore having absorption in a visible light region, and W is a chain alkylene group having 2 to 30 carbon atoms, a cyclic alkylene group having 3 to 30 carbon atoms, or a derivative of either alkylene group in which the number of carbon atoms in an additional structure of the alkylene group is equal to or less than the number of carbon atoms in the alkylene group.

3 . The thiol group-containing colored compound of claim 1 , wherein the chromophore includes at least one selected from the group consisting of an unsaturated alkyl group, an aromatic group, a heterocyclic ring, and a metal ion.

4 . The thiol group-containing colored compound of claim 1 , wherein the chromophore includes at least one selected from the group consisting of a nitroso group, a nitro group, an azo group, a methine group, an amino group, a ketone group, a thiazolyl group, a naphthoquinone group, an indoline group, a stilbene derivative, an indophenol derivative, a diphenylmethane derivative, an anthraquinone derivative, a triarylmethane derivative, a diazine derivative, an indigoid derivative, a xanthene derivative, an oxazine derivative, a phthalocyanine derivative, an acridine derivative, a thiazine derivate, a sulfur atom-containing compound, and a metal ion-containing compound.

5 . The thiol group-containing colored compound of claim 4 , wherein the chromophore includes at least one selected from the group consisting of a Cr complex, a Cu complex, a Co complex, a Ni complex, an Fe complex, an azo group, and an indoline group.

6 . A metal nanowire comprising a metal nanowire body, wherein at least a portion of a surface of the metal nanowire body is surface treated with the thiol group-containing colored compound of claim 1 .

7 . The metal nanowire of claim 6 , wherein the metal nanowire body comprises at least one element selected from the group consisting of Ag, Au, Ni, Cu, Pd, Pt, Rh, Ir, Ru, Os, Fe, Co, Sn, Al, Tl, Zn, Nb, Ti, In, W, Mo, Cr, Fe, V, and Ta.

8 . A dispersion liquid comprising:
the metal nanowires of claim 6 ; a solvent; and a binder.

9 . A transparent conductive film comprising the metal nanowires of claim 6 .

10 . The transparent conductive film of claim 9 , wherein the metal nanowires are dispersed in a transparent binder.

11 . The transparent conductive film of claim 9 , wherein a reflection L value of the transparent conductive film is 9 or less.

12 . The transparent conductive film of claim 9 , further comprising a metal nanowire body that is not surface treated with the thiol group-containing colored compound.

13 . An information input device comprising:
a transparent substrate; and the transparent conductive film of claim 9 disposed on the transparent substrate.

14 . An electronic apparatus comprising:
a display panel; and the transparent conductive film of claim 9 disposed on the display panel.

15 . The thiol group-containing colored compound of claim 2 , wherein the chromophore includes at least one selected from the group consisting of an unsaturated alkyl group, an aromatic group, a heterocyclic ring, and a metal ion.

16 . The thiol group-containing colored compound of claim 2 , wherein the chromophore includes at least one selected from the group consisting of a nitroso group, a nitro group, an azo group, a methine group, an amino group, a ketone group, a thiazolyl group, a naphthoquinone group, an indoline group, a stilbene derivative, an indophenol derivative, a diphenylmethane derivative, an anthraquinone derivative, a triarylmethane derivative, a diazine derivative, an indigoid derivative, a xanthene derivative, an oxazine derivative, a phthalocyanine derivative, an acridine derivative, a thiazine derivate, a sulfur atom-containing compound, and a metal ion-containing compound.
