Abstract
An organic semiconducting material comprises a naphthalocyanine derivative represented by formula (1); wherein M represents Si, Ge or Sn, R1 to R3 represent substituents other than a hydrogen atom except that all of R1 to R3 are identical straight-chain alkyl groups, and R4 to R27 each independently represents a hydrogen atom or a substituent.
Claims6
A film comprising a naphthalocyanine compound represented by formula (1):
- wherein
- M represents Si,
- R1 to R3 each represents an alkyl group having 1 to 30 carbon atoms, an aryl group having 6 to 30 carbon atoms, an alkoxy group having 1 to 30 carbon atoms, an amino group, an alkylamino group having 1 to 30 carbon atoms, or aniline group having 6 to 30 carbon atoms, and may be substituted, and
- R4 to R27 each independently represents a hydrogen atom or a substituent,
- wherein at least one of R1 to R3 is a branched alkyl group having 3 to 6 carbon atoms, an aromatic hydrocarbon group having 6 to 12 carbon atoms, or an aromatic heterocyclic group having 6 to 12 carbon atoms.
