A strategy for creating new association specificity of hydrogen-bonded duplexes by varying the spacings between neighboring hydrogen bonds is described. Incorporation of naphthalene-based residues has provided oligoamide strands that pair into duplexes sharing the same H-bonding sequences (e.g., DDAA) but differing in the spacings between their intermolecular hydrogen bonds, leading to homo- or heteroduplexes
描述了通过改变相邻氢键之间的间隔来产生氢键双链体的新缔合特异性的策略。萘基残基的掺入提供了寡酰胺链,其配对成具有相同的H键序列(例如DDAA)但其分子间氢键间距不同的双链体,从而导致同双链或异双链。这项工作所证明的操纵缔合特异性的能力可以扩展到其他多个氢键缔合系统,从而进一步增强了多个氢键缔合单元用于构建超分子结构的多样性。
