Abstract
Abstract A new group of fluorescent organic materials having a variety of uses are described. They are especially useful as dye compounds in dye laser systems, and as photochemical agents in the treatment of diseased tissues using photodynamic therapy techniques. The materials involve a tri-cyclic compound having the following structure: ##STR1## In this structure, R 1 -R 21 represent a variety of organic and inorganic groups.
