Abstract

Vacuum-deposited films of ω-(1-pyrenyl) alkanoic acids showed fluorescence spectral changes upon irradiation with an excimer laser and a Xe lamp, although no absorption spectral change was detected. It was confirmed that this characteristic phenomenon depends on the number of methylenes in the chain and that a non-linear photochemical process (with respect to irradiation intensity) is involved.
