, p. 1735 - 1739 (1984)
9-Methyl- (1a), 9-benzyl- (1b), 9-(diphenylmethyl)- (1c), and 9-ethylacridine (1d) were employed to obtain luminescent features of the acridines.The decay of chemiluminescence (CL) exhibits a pseudo-first order behavior with apparent rate constants 0.10,

Disclosed is a method of making substituted acridines. The method includes the step of reacting a bis(halophenyl) amine with an alkyne for a time and at a temperature to yield a substituted acridine.

The enthalpies and temperatures of melting of eight 9-substituted acridines (alkyl, aryl or alkoxy) (I) and six their 10-methylated-acridinium trifluoromethanesulphonate (II) derivatives were measured by DSC. The enthalpies and temperatures of volatilisation of the first group of compounds were also determined by DSC or obtained by fitting TG curves to the Clausius–Clapeyron relationship. By combining the enthalpies of formation of gaseous acridines or 10-methylacridinium trifluoromethanesulphonate ions, obtained by the DFT method, and the corresponding enthalpies of sublimation and/or crystal lattice enthalpies, the enthalpies of formation of the compounds in the solid phase were predicted. For compounds whose crystal structures are known, experimental enthalpies of sublimation correspond reasonably well to crystal lattice enthalpies predicted theoretically as the sum of electrostatic, dispersive and repulsive interactions. Analysis of crystal lattice enthalpy contributions indicates that dispersive interactions between molecules always predominate in the case of acridine derivatives, whilst the crystal lattices of their quaternary salts are stabilised by electrostatic interactions between ions. Only in the case of 9-bromomethylacridine derivative, which crystallises in the monohydrated form, electrostatic contribution to the crystal lattice energy is significantly higher than in the other investigated acridines.
