Procedure

Alternatively, the at least one 1,2-diaminobenzene compound and the 1,2,4,5-tetrahydroxybenzene compound are dissolved in a solvent to form a solution, and the solution is heated to form the 5,7,12,14-tetrahydro-5,7,12,14-tetraazapentacene compound. The solution can be heated at a temperature of from about 80° C. to about 180° C., and the solution can be heated for a time period of from about 30 minutes to about 12 hours.
