The products were identified by IR,NMR,MS and elemental analysis. In our method,K.OH was used in place of NaOH to synthesize benzyl ester of 3,5-dimethyl-4-hydroxybenzoic acid,2',6'-dimethyl-4'-(n-succinimidyloxycarbonyl) phenyl-acridinium-9-carboxylate was purified on a silica gel column with chloroform/ethylacetate(4:l,v/v) as eluent and further purified by triturating with hexane/acetone(2:l,v/v).The luminescence produced by DMAE-NHS is a flash light with maximumemission at 0.4s and decay half-time of 0.9s. The luminescence intensity is 6.11x10 cps/mol,which is affected by the composition of trigger and surfactant.
