“…Fluorenone derivatives are extensively studied as potential biomedical agents [134], mesomorphic compounds [5,6], photosensitizers [7,8], fluorophoric ligands [9312], and components of electrooptical materials [13315]. Wide application of these compounds is determined mainly by their high photoluminescence quantum yields and thermal stability.…”

The photochemical behavior of the 2-pyridyl phenyl ketone was studied by stationary techniques in sodium dodecyl sulfate submicellar and micellar solutions. Nanosecond laser flash photolysis was employed to identify the primarily produced transients. The photochemistry is mainly due to fast intramolecular photocyclization, followed by photoaddition of water, with no competition by hydrogen abstraction from the surfactants by the triplet ketone. The intramicellar water molecules are more reactive in photoaddition than bulk water molecules. Transient absorption spectra and lifetimes were determined. By using quenchers which are solubilized in the micelle (biphenyl) or in the bulk water (CuCl 2), intra-and extra-micellar processes were characterized.
