Abstract
The present disclosure provides a carbon material including a carbon-containing layer having opening parts; and a solid body provided so as to cover the opening parts of the carbon-containing layer, in which the solid body has hole parts communicating with the opening parts.
Claims17
A carbon material comprising:
- a carbon-containing layer having opening parts;
- and
- a plurality of solid bodies, each of the plurality of solid bodies provided so as to cover the opening parts of the carbon-containing layer;
- wherein each of the plurality of solid bodies is joined by TT-stacking to the carbon-containing layer;
- wherein each of the plurality of solid bodies has hole parts communicating with the opening parts;
- and
- wherein each of the plurality of solid bodies comprises at least one selected from the group consisting of:
- (i) a compound represented by the following General Formula (1),
- wherein each R1 is an alkyl group, an alkoxy group, or a polyoxyalkylene group;
- (ii) naphthalocyanine;
- (iii) anthracocyanine;
- (iv) azulenocyanine;
- (V) a compound represented by the following General Formula (2),
- wherein each R2 is an alkyl group, an alkoxy group, or a polyoxyalkylene group;
- (vi) a compound represented by the following General Formula (3),
- wherein each R3 is an alkyl group, an alkoxy group, or a polyoxyalkylene group;
- or
- (vii) a compound represented by the following General Formula (4),

A method for producing a carbon material, the method comprising:
- a first step of preparing a dispersion liquid including a carbon-containing layer, a plurality of metal complexes, and a solvent, reducing the content of the solvent, and thereby forming a composite having each of the plurality of metal complexes adhered to the surface of the carbon-containing layer,
- wherein each of the plurality of metal complexes is joined by TT-stacking to the carbon-containing layer;
- a second step of heat-treating the composite and providing opening parts in the carbon-containing layer in the vicinity of the metal atoms constituting each of the plurality of metal complexes;
- and
- a third step of removing at least a portion of the metal atoms constituting each of the plurality of metal complexes and then forming a solid body having hole parts communicating with the opening parts;
- wherein each of the plurality of metal complexes includes a metal atom and a complex of at least one selected from the group consisting of:
- (i) a compound represented by the following General Formula (1),
- wherein each R1 is an alkyl group, an alkoxy group, or a polyoxyalkylene group;
- (ii) naphthalocyanine;
- (iii) anthracocyanine;
- (iv) azulenocyanine;
- (v) a compound represented by the following General Formula (2),
- wherein each R2 is an alkyl group, an alkoxy group, or a polyoxyalkylene group;
- (vi) a compound represented by the following General Formula (3),
- wherein each R3 is an alkyl group, an alkoxy group, or a polyoxyalkylene group;
- or
- (vii) a compound represented by the following General Formula (4),
- wherein each R4 is an alkyl group, an alkoxy group, or a polyoxyalkylene group.
