Various novel acridinium ester derivatives having Ph and biphenyl moieties were synthesized and their optimal chemiluminescence conditions were investigated. Several strongly chemiluminescent acridinium esters under neutral conditions were found and then these derivatives were used to detect hydrogen peroxide and glucose. Acridinium esters having strong electron-withdrawing groups such as cyano, methoxycarbonyl and nitro groups at the 4-position of the Ph moiety in Ph 10-methyl-10λ4-acridine-9-carboxylate, trifluoromethane-sulfonate salt showed strong chemiluminescence intensities. The chemiluminescence intensity of 3,4-dicyanophenyl 10-methyl-10λ4-acridine-9-carboxylate, trifluoromethanesulfonate salt was approx. 100 times stronger than that of Ph 10-methyl-10λ4-acridine-9-carboxylate, trifluoromethanesulfonate salt at pH 7. The linear calibration ranges of hydrogen peroxide and glucose were 0.05-10 mM and 10-2000 μM using 3,4-(dimethoxycarbonyl)phenyl 10-methyl-10λ4-acridine-9-carboxylate, trifluoromethane-sulfonate salt at pH 7 and pH 7.5, resp. The proposed chemiluminescence reaction mechanism of acridinium ester via a dioxetanone structure was evaluated via quantum chem. calculation on d. functional theory. The proposed mechanism was composed of the nucleophilic addition reaction of hydroperoxide anion, the dioxetanone ring formation and nonadiabatic transition due to spin-orbit coupling around the transition state (TS) to the triplet state (T1) following the decomposition-pathway. The TS which appeared in the thermal decomposition would be a rate-determining step for all three processes.
