Peptides bearing beta-cyclodextrin and 4-(N,N-dimethylamino)benzoyl (DMAB) units in the peptide side chains were prepared as chemosensors for molecule detection. The DMAB unit was expected to be included into the cyclodextrin cavity intramolecularly. However, these peptides exhibited no twisted intramolecular charge transfer fluorescence and the normal fluorescence intensity decreased upon the addition of 1-adamantanol as an exogenous guest, indicating that the DMAB units are shallowly included in the cyclodextrin cavities.
