Procedure

In some particular embodiments, one molar unit of the 1,2,4,5-tetrahydroxybenzene compound is reacted with about one molar unit of a first 1,2-diaminobenzene compound to form an intermediate, and the intermediate is subsequently reacted with about one molar unit of a second 1,2-diaminobenzene compound to form the 5,7,12,14-tetrahydro-5,7,12,14-tetraazapentacene compound. The first 1,2-diaminobenzene compound and the second 1,2-diaminobenzene compound are different.
