Pseudopeptide-based bioinspired materials
are emerging
for selective
recognition of biologically significant analytes and are applicable
in the modern nanoscience field. Therefore, we have developed novel
multifunctional C2-symmetric soft pseudopeptides
by amino acid l-valine and salicylaldehyde fragments using
a series of aliphatic linkers. They are highly selective and sensitive
to Zn (II) ions under physiological conditions and reveal significant
fluorescence enhancement with the PET mechanism. The molecular self-assembly
shows zinc-induced morphological transformation of the rod-shaped
assembly into a chain-like morphology. Such a metal-induced hierarchical
nano-assembly may have relevance for specific nanobiotechnology applications.
