Because of their wide number of biological functions and potential applications, self-assembled nanotubes constitute highly relevant targets in noncovalent synthesis. Herein, we introduce a novel approach to produce supramolecular nanotubes with defined inner and outer diameters from rigid rod-like monomers programmed with complementary nucleobases through two distinct, decoupled cooperative processes of different hierarchy and acting in orthogonal directions: chelate cooperativity, responsible for the formation of robust Watson-Crick H-bonded cyclic tetramers, and nucleation-growth cooperative polymerization.
由于其广泛的生物学功能和潜在应用，自组装纳米管成为非共价合成中高度相关的目标。在此，我们引入了一种新方法，通过具有互补碱基的刚性棒状单体，经过两个不同层次且相互正交的协同过程，制备具有确定内径和外径的超分子纳米管：螯合协同作用，负责形成稳定的沃森-克里克氢键环状四聚体；成核-生长协同聚合。
