abstract

The absorption and fluorescence of free base, tetraphenyl-substituted porphyrins are shown to be sensitive to exposure to NO2. The Soret band absorption red-shifts and fluorescence is quenched by an order of magnitude. The fluorescence spectrum of a gassed sample is also red-shifted and broadened following exposure. Several solid state embodiments of a fluorescent sensor based upon free base porphyrins are proposed.
