Novel binding mode for fluorinated porphyrins: synthesis and fluorophilic affinity of stable atropoisomers of 5,10,15,20-tetrakis[2-(perfluoroacyl)aminophenyl]-21H,23H-porphyrins

The synthesis and binding properties of 5,10,15,20-tetrakis[2-(perfluoroacyl)aminophenyl]-21H,23H-porphyrins as new types of fluorophilic receptors for potential application as optical sensors are reported. The observed remarkable binding affinity for fluorinated substrates monitored by vis spectroscopy represents a novel binding mode in porphyrin chemistry.
