我们成功地在获得了不断水解的AMPPD中间体的碱性水溶液的光致发光光谱
并将其与AMPPD化学发光光谱进行比对
得出了其光致发光光谱与化学发光光谱在误差范围内峰位基本一致的结论。该研究结果对正确地认识AMPPD在碱性水溶液中化学发光的机理
并进一步合理地设计高效的化学发光体系具有重要意义。
In order to design more effective chemiluminescent systems in aqueous solution
it is essential to get a complete image of the luminescent dynamic process. In this work
taking AMPPD molecule as an example
the photoluminescence of the AMPPD authentic emittermethyl m-oxybenzoate anion in aqueous solvent was systematically studied. By measuring the steady-state and time-resolved spectra
and
1
H NMR signal of the authentic emitter solution
the photoluminescence spectrum of the authentic emitter was successfully extracted out. And the result revealed that the photoluminescence spectrum peak of the authentic emitter is coincided with that of its chemiluminescence spectrum within the error range. These results make the meaning on chemiluminescence dynamics of AMPPD more clear
and further will facilitate the design of more effective chemically initiated electron exchange luminescence (CIEEL) systems.
