一维 (1D) 配位聚合物 (CP) 在剥离成单个链方面存在局限性，这阻碍了它们作为功能性 1D 纳米材料的实用性。在这里，我们合成了具有双(二吡啶)锌(II)络合物基序的手性一维CP。在有机介质中超声处理后，它们可以剥落成单链，保留长达 3.19 μm（约 2600 个单体单元）的长度。它们的手性光学结构使剥离的线能够显示出圆偏振发光，其强度是参考单体复合物的 5.9 倍。
One-dimensional (1D) coordination polymers (CPs) experiences limitations in exfoliation into individual strands, which hamper their utility as functional 1D nanomaterials. Here we synthesize chiral 1D-CPs that feature the bis(dipyrrinato)zinc(II) complex motif. They can be exfoliated into single strands upon sonication in organic media, retaining lengths of up to 3.19 mu m (ca. 2600 monomer units). Their chiroptical structure allows the exfoliated wires to show circularly polarized luminescence at an intensity 5.9 times that of reference monomer complexes.
