Molecular Self-Assembly (IMAGE) University at Buffalo Caption The new catalyst, a cofacial cobalt porphyrin, is created using a process called molecular self-assembly. During this process, a vial filled with molecules called cobalt porphyrins (vial on the left) are mixed with a vial of ruthenium 'clips' (vial in the center). The end product, the cofacial cobalt porphyrin catalyst, is pictured in the vial at the right.
