EFFECTS OF MACROMOLECULAR ASSOCIATION ON FLUORESCENCE AND PHOTODIMERIZATION BEHAVIORS OF POLYMERIC ANTHRACENE CHROMOPHORE IN AN AQUEOUS SOLUTION
Anthracene chromophore attached to the chain end of poly(ethylene glycol) (PEG-Ant) was found to exhibit excimer fluorescence down to 10−7 M in an aqueous solution. Macromolecular association of PEG-Ant with poly(methacrylic acid) (PMAA) increased excimer emission intensity by a factor of 10 as well as the rate of photodimerization.
