Four diamino acid‐N α ‐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.
