Abstract
Official abstract text for this publication.
A compound represented by the following general formula (1) is used as a precursor of a graphene nanoribbon: where X's are independent of each other and are leaving groups, R's are independent of one another and are hydrogen atoms, fluorine atoms, chlorine atoms, or 1-12C straight-chain, branched-chain, or cyclic alkyl groups, and each of p, q, r, and s is an integer in the range of 0 to 5.
First claim
Opening claim text (preview).
What is claimed is: 1. A compound represented by the following general formula (1): wherein X's are independently selected from bromine atoms, chlorine atoms, or iodine atoms, R's are independently selected from hydrogen atoms, fluorine atoms, chlorine atoms, or 1-12C straight-chain, branched-chain, or cyclic alkyl groups, and each of p, q, r, and s is an integer in the range of 0 to 5. 2. A compound fabrication method comprising: performing coupling between a first compound comprising an amino group and a nitro group represented by the following general formula (2) and a second compound represented by the following general formula (3), converting the amino group to a leaving group, and synthesizing a third compound; and performing coupling between the third compound and a fourth compound represented by the following general formula (4), converting the nitro group to a leaving group selected from a bromine atom, a chlorine atom, or an iodine atom, and synthesizing a fifth compound represented by the following general formula (5), wherein: in the general formula (2), X's are independent of each other and are leaving groups; in the general formula (3), R's are independently selected from hydrogen atoms, fluorine atoms, chlorine atoms, or 1-12C straight-chain, branched-chain, or cyclic alkyl groups, Z is a boronyl group, a bromine atom, or an iodine atom, and each oft and u is an integer in the range of 0 to 5; in the general formula (4), X is a leaving group selected from a bromine atom, a chlorine atom, or an iodine atom, and Z is a boronyl group, a bromine atom, or an iodine atom; and in the general formula (5), X's are leaving groups independently selected from bromine atoms, chlorine atoms or iodine atoms, R's are independently selected from hydrogen atoms, fluorine atoms, chlorine atoms, or 1-12C straight-chain, branched-chain, or cyclic alkyl groups, and each of p, q, r, and s is an integer in the range of 0 to 5. 3. The compound fabrication method according to claim 2 , further comprising, after the synthesizing of the fifth compound, synthesizing a derivative of the fifth compound. 4. A graphene nanoribbon fabrication method comprising synthesizing a graphene nanoribbon represented by the following general formula (7) by polymerization of a plurality of compounds represented by the following general formula (6) and aromatic cyclization, wherein: in the general formula (6), X's are leaving groups independently selected from bromine atoms, chlorine atoms or iodine atoms, R's are independently selected from hydrogen atoms, fluorine atoms, chlorine atoms, or 1-12C straight-chain, branched-chain, or cyclic alkyl groups, and each of p, q, r, and s is an integer in the range of 0 to 5; and in the general formula (7), R's are independently selected from hydrogen atoms, fluorine atoms, chlorine atoms, or 1-12C straight-chain, branched-chain, or cyclic alkyl groups and each of p, q, r, and s is an integer in the range of 0 to 5.
