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.

用于精确调节纳米组装的锌诱导发光 L-缬氨酸基拟肽软仿生材料

基于伪肽的仿生材料正在出现，用于选择性识别具有生物学意义的分析物，并适用于现代纳米科学领域。因此，我们利用一系列脂肪族接头，通过氨基酸L-缬氨酸和水杨醛片段开发了新型多功能C _{2对称软伪肽。}它们在生理条件下对 Zn (II) 离子具有高度选择性和敏感性，并通过 PET 机制显示出显着的荧光增强。分子自组装显示锌诱导棒状组装体形态转变为链状形态。这种金属诱导的分层纳米组装可能与特定的纳米生物技术应用相关。
