Study of Chemiluminescence Characters of DMAE·NHS

Chemiluminescence characters of DMAE·NHS has been investigated, showing that luminescence produced by DMAE·NHS being a flash light with maximum emission at 0.4s and decay half-time of 0.9s, with the luminescence intensity of 6.11×10 18 cps/mol,which is affected by the composition of trigger and surfactant.In aqueous solution, heat stablility of DMAE·NHS decreases with the increase of pH value and temperature due to its decomposition by hydrolysis.
