Dipyrrolyldiketone boron complexes linked by a disulfide bond were synthesized, forming H-aggregated dimers assisted by intramolecular π–π and hydrogen-bonding interactions. The conformations of the dimers, with small C–S–S–C dihedral angles, were examined by UV–vis absorption and 1H NMR spectra as well as single-crystal X-ray analysis and theoretical studies.
