| Abstract: | Four diamino acid-Nalpha-substituted oligopeptide (DNO) oligomers substituted with pyrenyl as photophysical probes were synthesized. The excimer formation and ground-state association of the pyrenyl groups were investigated by means of absorption and steady-state fluorescence spectroscopy together with time-resolved fluorescence techniques. The photophysical parameters obtained from the different derivatives reflect the secondary structural properties of the DNO backbones. |
