    • −8 M; moreover, only a small bathochromic shift of these spectra is observed when axial ligands such as pyridine are added. The absorptive and emissive propertles of these chromophores stand in sharp contrast to examples of butadiynyl‐bridged porphyrins reported by Anderson, who has demonstrated that axial ligation is required to prevent association of conjugated porphyrin arrays derived from β‐alkyl‐substituted porphyrin building blocks (ref. [13b]).

    • A point‐dipole analysis of the optical spectra of these systems corroborates a picture in which the porphyrin‐porphyrin geometrical relationships within the supermolecule are approximately coplanar (ref. [4]).

    • Excitation spectra for compounds 1–7 mirror their absorption spectra as expected from Kasha's rule, while compound 8 exhibits a diminished emissive signal at long wavelength.
