Effects of some trivalent metal ions on the fluoride-induced chemiluminescence from a phenylphosphate-substituted dioxetane Lumigen PPD.
The chemiluminescence generated from the reaction of a thermally stable phenylphosphate-substituted dioxetane Lumigen PPD at ambient temperature was studied in DMSO solution. The presence of trivalent metal ions Cr(3+), Ga(3+), Fe(3+) and Al(3+) was found to quench the resulting chemiluminescence dramatically. The system resulted in nice Stern-Volmer plots in the quencher concentration range 1.5 x 10(-4)-1.8 x 10(-3) mol/L. The K(Q) values decreased in the order Cr(3+) > Ga(3+) > Fe(3+) > Al(3+).
