While the photolysis of 1-pyrenylmethyl phenylacetates in methanol gave the original phenylaceticacids, irradiation of the 1-naphthoate and 9-anthracenecarboxylate leads to the formation of the intramolecular exciplexes that are inert to the photolysis. The Φf and τf values of these esters have been determined.
A fluorescence quenching based oxygen sensor can be prepared comprising a polystyrene polymer linked to pyrene. The fluorescence based sensor has the formula (I),
Polystyrene-Y-R-Pyrene ; (I)
whereinY is fluorescence quenching
and R is an aliphatic linking group having 1 to 11 carbon atoms. The sensor can be coated onto a support and integrated with an LED excitation source and fluorescence detector.
