The dynamic behavior of a porphyrin dimer, based on the covalent linkage of two macrocyclic moieties with a butadiyne connector, was studied in thin films by UV-visible and emission spectroscopies. The degree of π-conjugation through control of intramol. motion was studied without employing extreme conditions such as cryogenic temperatures or high viscosity. By exploiting the propensity of the dimer to bind axial ligands through Zn-N bonds, the coplanar and orthogonal conformations of the dimer may be stabilized in ultrathin films at the air/water interface. Also, using the Langmuir-Blodgett technique, monolayer-thick matrix-free films on solid substrates containing the porphyrin dimer were obtained. In the latter case, the dimer exists in either an exclusively coplanar state or a mixture of conformational states depending on the nature of the axial ligand: 1,4-diazabicyclo[2.2.2]-octane (DABCO) or 4-aminomethylpyridine (AMP).
