Abstract
A photoelectric conversion device that uses a compound represented by the general formula (1) in the hole transport layer has excellent heat resistance. R1 is an aromatic hydrocarbon group, a heterocyclic group, etc., and R2 to R29 each are a hydrogen atom, an alkoxy group, etc.
Claims8
A compound represented by the following general formula (1):
- wherein:
- R1 represents a hydrogen atom, a halogen atom, a hydroxyl group,
- a linear or branched alkyl group with 1 to 20 carbon atoms, which may have a substituent,
- a linear or branched alkenyl group with 2 to 20 carbon atoms, which may have a substituent,
- a linear or branched alkoxy group with 1 to 20 carbon atoms, which may have a substituent,
- an aryloxy group with 6 to 30 carbon atoms, which may have a substituent,
- an amino group with 0 to 60 carbon atoms, which may have a substituent,
- a thio group with 0 to 20 carbon atoms, which may have a substituent,
- a monovalent aromatic hydrocarbon group with 6 to 30 carbon atoms, which may have a substituent, or
- a monovalent heterocyclic group with 5 to 30 ring-forming atoms, which may have a substituent,
- R2 to R29 each independently represent:
- a hydrogen atom,
- a linear or branched alkyl group with 1 to 20 carbon atoms, which may have a substituent,
- a linear or branched alkenyl group with 2 to 20 carbon atoms, which may have a substituent,
- a cycloalkyl group with 3 to 12 carbon atoms, which may have a substituent,
- a linear or branched alkoxy group with 1 to 20 carbon atoms, which may have a substituent,
- an amino group with 0 to 20 carbon atoms, which may have a substituent, or
- a thio group with 0 to 20 carbon atoms, which may have a substituent.
