Abstract
The compound 1-(9-anthrylmethyl)pyridinium chloride contrasts with most anthracene derivatives in showing no fluorescence. It is established that the anthracene fluorescence is quenched at a diffusion controlled rate by pyridinium ion, indicating that the non-fluorescence of the compound results from a quasi-free interaction of the attached pyridinium moiety. Corrections for internal absorption are clarified.Keywords
