Molecular tweezers built from sawhorse‐type dinuclearruthenium units and carboxyphenyl porphyrin derivatives{5‐(4‐carboxyphenyl)‐10,15,20‐triphenyl‐21H,23H‐porphyrin,[5‐(4‐carboxyphenyl)‐10,15,20‐triphenylporphyrin]zinc, 5,10‐bis(4‐carboxyphenyl)‐15,20‐diphenyl‐21H,23H‐porphyrin, and [5,10‐bis(4‐carboxyphenyl)‐15,20‐diphenylporphyrin]zinc} are presented. Molecular modeling shows that in all cases the two porphyrin moieties are adequately positioned to encapsulate guest molecules. Therefore, the host–guest interactions between the sawhorse‐type tetracarbonyldiruthenium tweezers and different guest molecules [fullerene (C 60 ), pyridine (pyr), 4,4′‐bipyridine (bpy), 1,2‐bis(4‐pyridyl)ethylene (bpe), 5,10‐bis(4‐pyridyl)‐15,20‐diphenyl‐21H,23H‐porphyrin (5,10‐dpp), and 5,15‐bis(4‐pyridyl)‐10,20‐diphenyl‐21H,23H‐porphyrin (5,15‐dpp)] have been studied in solution by using optical spectroscopic methods.
