STUDIES OF THE ANTENNA EFFECT IN POLYMER MOLECULES ENERGY MIGRATION AND TRAPPING IN NAPHTHALENE-CONTAINING POLYELECTROLYTES*

Received Date: 14 November 1997

Polymers of 1- and 2-vinylnaphthalene containing more than about 50mol% sulfonic acid groups dissolve in water to form "hypercoiled" conformations whichhave many of the properties of micelles. Hydrophobic molecules such as anthracene andperylene are selectively absorbed in these pseudo micellar structures, and their fluorescenceemission is sensitized by energy transfer from the surrounding naphthalene chromophores.When irradiated with UV light in the presence of oxygen, the emission of perylene rapidly decreases.It is proposed that this is due to reaction of singlet oxygen with the perylene trapped in the hypercoiled polymer.
