Chemiluminescent mixtures utilizing tri and tetra alkyl substituted 9,10-bis(phenylethynyl)anthracene derivatives to provide higher chemiluminescence efficiencies in low temperature and high intensity-short duration applications. The preferred fluorescers are 1,2,4-trimethyl-9,10-bis(phenylethynyl) anthracene and 1,2,3,4- tetramethyl-9,10-bis(phenylethynyl)anthracene, which compounds are also part of the instant invention. |
