Abstract
Abstract Fluorescers for use in chemiluminescent mixtures having aqueous or organic solvent systems. The compounds have the formula ##STR1## wherein m is an integer from 1 to 5, n is an integer from 1 to 20, and R represents hydrogen, or C 1 -C 5 alkyl. In the preferred embodiments m is 1, n is 5, and R is methyl, or hydrogen.
