a modified Eglinton–Galbraith coupling and a sacrificial building block. We demonstrate the versatility of this approach by preparing hexaynes functionalized with phosphonic acid, carboxylic acid, ammonium, or thiol head groups, which serve as neutral, cationogenic, or anionogenic interfacially active groups. We show that these hexaynes are carbon‐rich amphiphiles or bolaamphiphiles that self‐assemble
具有两个或多个共轭碳-碳三键的寡炔是富碳纳米材料的有用前体。然而,迄今为止,它们的应用范围受到具有挑战性的合成的严重限制,特别是在具有官能团的低聚炔的情况下。在这里,我们报告了通过使用改良的Eglinton-Galbraith耦合和牺牲构件,对对称和不对称功能化己炔的通用合成方法。我们通过制备用
膦酸,
羧酸,
铵或
硫醇头基团官能化的己炔,证明了这种方法的多功能性,它们可充当中性,阳离子型或阴离子型界面活性基团。我们证明这些己炔是富碳的两亲物或两亲物,它们在液-液界面处自组装,
