We report a two-step synthesis for N-aryl- and N-alkyl-substituted 4-piperidones, 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 for solvent polarity.

Efficient photoinduced charge separation can occur in molecules containing electron donor (D) and acceptor (A) groups separated by an elongated paraffinic spacer. For two molecules of this type the dipole moment of the excited state thus achieved (D** plu
