Composition using them new dibenzofulvene derivative monomer, and new dibenzofulvene derivative

摘要

PPROBLEM TO BE SOLVED: To provide a novel dibenzofulvene derivative monomer excellent in charge transport ability and having a fluorene residue as a side chain, to provide a novel dibenzofulvene derivative, and to provide compositions and charge transport materials using them. PSOLUTION: Provided is a composition containing a dibenzofulvene derivative comprising 10-100 mol.% structural units each represented by the formula (wherein ArSP1/SPand ArSP2/SPare each an aromatic ring; RSP1/SPand RSP2/SPare each a hydrogen atom or a group having a hetero ring structure except an aromatic ring, provided that at least either of RSP1/SPand RSP2/SPis a group having a hetro ring except an aromatic ring; RSP3/SPand RSP4/SPare each a hydrogen atom, an alkyl group, an aromatic group, a cyano ring, or an ester-linkage containing organic group; and XSP1/SPis a single bond, -CHSB2/SB-. -CSB2/SBHSB4/SB-, -CH=CH-, -CO-, or a hetero atom) and an electron-accepting compound or an electron-donating compound.
