摘　　要：Polymers of 1- and 2-vinylnaphthalene containing more than about 50 mol% sulfonic acid groups dissolve in water to form 'hypercoiled' conformations which have many of the properties of micelles. Hydrophobic molecules such as anthracene and perylene are selectively absorbed in these pseudo micellar structures, and their fluorescence emission 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.
