Abstrakt: The structure-quenching relationship in 9-aminoalkylanthracenes is examined by the synthesis and fluorescence evaluation of five derivatives; it is observed that benzylic 2° and 3° amines lead to =95% quenching of anthracene fluorescence in water, while other amines afford substantially lower quenching efficiencies.
