Through a combination of rational design and synthetic serendipity, two new structural isomers of the dithienoborepin (DTB) architecture have been realized. Unlike previous members of this family, these boron-containing polycyclic aromatics are unsymmetrical with respect to the fusion orientation of the central borepin and flanking thiophene rings. Characterization of the unsymmetrical dithienoborepins through
