The bicarbazole compound represented by General Formula (G0) can be synthesized by a simple synthesis scheme as follows. For example, as shown below in Scheme (a), a halogen compound of a benzofuropyrimidine including a substituent including one condensed ring or two condensed rings or a halogen compound of a benzothienopyrimidine including a substituent including one condensed ring or two condensed rings (A1), or a dihalogen compound of a substituted or unsubstituted benzofuropyrimidine or a dihalogen compound of a substituted or unsubstituted benzothienopyrimidine (A1′) reacts with an arylboronic acid compound of a bicarbazole derivative (A2) or a bicarbazole derivative (A2′) to form the compound represented by General Formula (G0). Alternatively, the compound represented by General Formula (G0) may be obtained in such a manner that an intermediate (B2) is obtained through a reaction with a halogen-substituted aryl boronic acid (B1) and then made to react with the bicarbazole derivative (A2′), as shown below in Scheme (b). Alternatively, the compound represented by General Formula (G0) may be obtained in such a manner that an intermediate (C1) is obtained through a reaction with one of halogens of the dihalogen compound of a substituted or unsubstituted benzofuropyrimidine or the dihalogen compound of a substituted or unsubstituted benzothienopyrimidine (A1′) and one of the arylboronic acid compound of a bicarbazole derivative (A2) and the bicarbazole derivative (A2′) and then made to react with a boronic acid compound of a derivative including one condensed ring or two condensed rings (C2), as shown below in Scheme (c).
