in which the N substituent can easily be varied. A number of intramolecular donor-acceptor systems was synthesized from these piperidones by conversion of the carbonyl functionality. The influence of the N-aryl donor on the electronic absorption and fluorescence spectra was investigated systematically. It was concluded that some systems can be used as efficient fluorescent probes with a high sensitivity
我们报告了N-芳基和N-烷基取代的4-哌啶酮的两步合成法,其中N取代基很容易改变。通过羰基官能团的转化,由这些哌啶酮合成了许多分子内供体-受体系统。系统地研究了N-芳基供体对电子吸收和荧光光谱的影响。结论是,某些系统可以用作对溶剂极性具有高灵敏度的高效荧光探针。
