A pentafluorophenol active-ester porphyrin has been synthesised and covalently attached to an aminopropylsilylated glass surface by amide bond formation. Zinc is inserted into the surface-bound porphyrins and their interaction with amine ligands is investigated by UV–VIS spectroscopy. The high affinity of the zinc porphyrin monolayers for bidentate ligands such as 1, 4-diazabicyclo [2.2. 2] octane, 4, 4′-bipyridyl and 1, 3-di (4-pyridyl) propane ...
