    • Meyerhoffs TPP-based silica gel may also be used to separate neutral aromatic species such as naphthalene, anthracene, imidazole, and pyridine. In this case, π-π interactions between TPP and the neutral substrates probably play a critical role in mediating the separation process (see ref 7a).

    • Porphyrins are tetrapyrrolic, 18-π-electron, aromatic macrocycles that possess an inner core radius of 2.0 Å. This core size presumably prevents protonation at physiological pH as monoprotonated porphyrin is observed at pH <4. See refs 17b and 19b.
