ABSTRACT:
The object of the present invention is to provide a composition for conductive materials from which a conductive layer having a high carrier transport ability can be made, a conductive material formed of the composition and having a high carrier transport ability, a conductive layer formed using the conductive material as a main material, an electronic device provided with the conductive layer and having high reliability, and electronic equipment provided with the electronic device. The composition for conductive materials of the present invention comprising a compound represented by the following general formula (A1): wherein two R1s may be the same or different and each independently represents a straight-chain alkyl group having 2 to 8 carbon atoms, four R2s may be the same or different and each independently represents a hydrogen atom, a methyl group, or an ethyl group, Y represents a group containing at least one substituted or unsubstituted aromatic hydrocarbon ring or substituted or unsubstituted heterocycle, and two X1s may be the same or different and each independently represents a substituent represented by the following general formula (A2): wherein n′ is an integer of 3 to 8, m1s an integer of 0 to 3, and Z1represents a hydrogen atom, a methyl group or an ethyl group.
