Abstract
Fluorescence spectra and fluorescence decay kinetics of intramolecular excimers of di(1-pyrenylmethylene)adipate (DPA) and di(1-pyrenylmethylene)ether (DPE) were studied in Langmuir-Blodgett (LB) monolayers consisting of stearic acid (SA) and dipalmitoylphosphatidylcholine (DPPC). Two types of excimers with different lifetimes and different lifetime dependences on temperature were found for both of the compounds. No quenching of excimer fluorescence by oxygen was observed in LB films with SA as the matrix compound. When DPPC was used as a matrix only one type of excimer was quenched by oxygen. Photolysis of DPA and DPE LB films resulted in a dramatic decrease in excimer fluorescence, but negligible changes in the pyrene absorption band.
