Various novel acridinium ester derivatives having phenyl 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 at the 4-position of the phenyl moiety in phenyl 10-methyl-10λ4-acridine-9-carboxylate trifluoromethanesulfonate salt showed strong chemiluminescence intensities. The chemiluminescence intensity of 3,4-dicyanophenyl 10-methyl-10λ4-acridine-9-carboxylate trifluoromethanesulfonate salt was approximately 100 times stronger than that of phenyl 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 trifluoromethanesulfonate salt at pH 7 and pH 7.5, respectively. The proposed chemiluminescence reaction mechanism of acridinium ester via a dioxetanone structure was evaluated via quantum chemical calculation on density functional theory. The proposed mechanism was composed of the nucleophilic addition reaction of hydroperoxide anion, 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.

10-Methyl-9-(phenoxycarbonyl)acridinium trifluoromethanesulfonates bearing alkyl substituents at the benzene ring were synthesized, purified, and identified. In the reaction with OOH- in basic aqueous media, the cations of the compounds investigated were converted to electronically excited 10-methyl-9-acridinone, whose relaxation was accompanied by chemiluminescence (CL). The kinetic constants of CL decay, relative efficiencies of light emission, chemiluminescence quantum yields, and resistance toward alkaline hydrolysis were determined experimentally under various conditions. The mechanism of CL generation is considered on the basis of thermodynamic and kinetic parameters of the reaction steps predicted at the DFT level of theory. The chemiluminescence efficiency is the result of competition of the electrophilic center at C(9) between nucleophilic substitution by OOH - or OH- and the ability of the intermediates thus formed to decompose to electronically excited 10-methyl-9-acridinone. Identification of stable and intermediate reaction products corroborated the suggested reaction scheme. The results obtained, particularly the dependency of the "usefulness" parameter, which takes into account the CL quantum yield and the susceptibility to hydrolysis, on the cavity volume of the entity removed during oxidation, form a convenient framework within which to rationally design chemiluminescent 10-methyl-9-(phenoxycarbonyl)acridinium cations.
Vibrational spectra of phenyl acridine-9-carboxylates and their 10-methylated cations: A theoretical and experimental study

experimental part, p. 1546 - 1551 (2010/06/21)
Infrared spectra of phenyl acridine-9-carboxylates and their 10-methylated cationic derivatives were recorded and discussed. Experimental data were compared with theoretically predicted transitions at the DFT level of theory (using the B3LYP functional and 6-31G** basis set) for optimized geometries of molecules. Substitution influences the values of the wavenumbers of characteristic stretching and bending modes, i.e. those corresponding to ester groups and fragments of molecules containing a heterocyclic nitrogen atom. The experimentally determined transitions of selected groups of atoms correlate well with the theoretically predicted values. Interdependences among some theoretically derived physicochemical features of the compounds and IR frequencies of selected bands are also discussed.

Acridinium compounds as chemiluminogenic label
-
, (2008/06/13)
New acridinium compounds are provided which comply with formula 1, wherein A is a divalent organic moiety, such as an alkylene chain, X is a group which can be transformed together with C-9 of the acridine into a dioxetane by reaction with hydrogen peroxide, such as an aryloxy group, Y is a counter ion, and Z is a functional group, such as a carboxyl derivative. These acridinium compounds are useful as chemiluminogenic labels for both heterogeneous and homogeneous immunoassays.
Chemiluminescence Involving Acidic and Ambident Ion Light Emitters. The Chemiluminescence of the 9-Acridinepercarboxylate Anion

The reaction of phenyl 9-acridinecarboxylate (1) with an excess of peroxide ion in THF/water (67/33 mol percent) leads to the emission of either bright yellow-green light or bright blue light, depending on the reaction conditions.The blue emission is favored by high concentrations of hydrogen peroxide and water, for example. 9-Acridinepercarboxylic acid is a common intermediate in the reactions.The light emitter responsible for the blue chemiluminescence is acridone, whereas that responsible for the yellow-green chemiluminescence is the anion of acridone.The effects of base concentration and solvent composition on the relative proportions of these two emitters have produced evidence that, contrary to the expectation of simple theory, a dioxetanone is not an intermediate in the reaction.Other cases where chemiluminescence may involve percarboxylate and peroxide ions are discussed.
