Abstract
A graphene nanoribbon represented by formula (1): wherein R1 represents a linear alkyl group having 1 to 12 carbon atoms, R3 and R4 are both hydrogen atoms, or R3 and R4 taken together form a group represented by —SiR2aR2b—, wherein R2a and R2b are the same or different, and each represents a hydrogen atom, an optionally branched alkyl group having 1 to 4 carbon atoms, or a phenyl group, and n represents an integer of 1 or more, is a novel GNR obtained by a simpler and industrially advantageous method for GNRs.
Claims6
A graphene nanoribbon represented by formula (1):
- wherein R1 represents a linear alkyl group having 1 to 12 carbon atoms, R3 and R4 are both hydrogen atoms, or R3 and R4 taken together form a group represented by —SiR2aR2b—, wherein R2a and R2b are the same or different, and each represents a hydrogen atom, an optionally branched alkyl group having 1 to 4 carbon atoms, or a phenyl group, and n represents an integer of 1 or more.
A graphene nanoribbon obtained by polymerizing a silole compound represented by formula (2):
- wherein R1 represents a linear alkyl group having 1 to 12 carbon atoms, and R2a and R2b are the same or different, each represents a hydrogen atom, an optionally branched alkyl group having 1 to 4 carbon atoms, or a phenyl group,
- in the presence of 0.01 to 0.4 mol, based on 1 mole of silole compound represented by formula (2), of a palladium compound, o-chloranil, and a silver compound.
A silole compound represented by formula (3):
- wherein n-Bu represents an n-butyl group, and R2a and R2b are the same or different, and each represents a hydrogen atom, an optionally branched alkyl group having 1 to 4 carbon atoms, or a phenyl group.
