An optically active acylhydrazine-functionalized biphenyl (AHB) bearing L-alanine-derived oligoamide side chains with tris(alkoxy)phenyl residues at the periphery supramolecularly coassembles with its achiral AHB to form a one-dimensional helical nanofiber, in which intermolecular hydrogen bonding between the chiral/achiral oligoamide pendant units result in modest chiral amplification (the sergeants-and-soldiers effect). The chiral and achiral AHBs copolymerize with 2,6-pyridinedicarboxaldehyde to form preferred-handed helical copolymers with amplification of the helical sense excess driven by intramolecular hydrogen bonds.

手性和非手性酰基肼官能化联苯及其共聚物的超分子组合的手性放大

具有L-丙氨酸衍生的低聚酰胺侧链的光学活性酰基肼官能化联苯 (AHB)与外围具有三(烷氧基)苯基残基的低聚酰胺侧链与其非手性 AHB 超分子共组装形成一维螺旋纳米纤维,其中分子间氢键手性/非手性寡酰胺悬垂单元导致适度的手性放大(中士和士兵效应)。手性和非手性 AHB 与 2,6-吡啶二甲醛共聚形成优先手螺旋共聚物,由分子内氢键驱动的螺旋有义过剩的放大。
