Abstract
Abstract Bis(p-alkylphenylethynyl)anthracenes are described for use as fluorescer components in chemiluminescent reaction mixtures and in precursor solutions or solid mixtures. Chemiluminescent mixtures comprising these fluorescers are shown to generate higher light capacity and higher quantum yields than those made with similar prior art fluorescers.
