摘要： Coordinating additives are included in porpliyrinoid-based materials to promote intermolecular organization and improve one or more photoelectric characteristics of the materials, The coordinating additives are selected from fullerene compounds and organic compounds having free electron pairs. Combinations of different coordinating additives can be used to tailor the characteristic properties of such porphyrinoid-based materials, including porphyrin oligomers. Bidentate ligands are one type of coordinating additive that can form coordination bonds with a central metal ion of two different porphyrinoid compounds to promote porphyrinoid alignment and/or pi-stacking. The coordinating additives can shift the absorption spectrum of a photoactive material toward higher wa velengths, increase the external quantum efficiency of the material, or both.
