我们报告的遥爪聚（α-烯烃）和聚（环辛烯）均聚物的开环易位聚合（ROMP）和随后的功能化和嵌段共聚物的形成基于非共价相互作用的合成。而所有的聚（异戊烯）含有金属络合物或沿着聚合物侧链的氢键部分，以及在聚合物链的一个末端处的单个基于氢键的分子识别部分。这些均聚物允许通过自组装形成侧链官能化的AB和阿坝嵌段共聚物。通过（1）H NMR谱和等温滴定量热法证明了所有侧链和主链自组装事件的正交性质。所得到的完全官能化的嵌段共聚物是第一种结合侧链和主链自组装的共聚物，从而提供对共聚物官能化和结构的高度控制，并使合成材料更接近自然界中发现的动态自组装结构。
We report the synthesis of telechelic poly(norbornene) and poly(cyclooctene) homopolymers by ring-opening metathesis polymerization (ROMP) and their subsequent functionalization and block copolymer formation based on noncovalent interactions. Whereas all the poly(norbornene)s contain either a metal complex or a hydrogen-bonding moiety along the polymer side-chains, together with a single hydrogen-bonding-based molecular recognition moiety at one terminal end of the polymer chain. These homopolymers allow for the formation of side-chain-functionalized AB and ABA block copolymers through self-assembly. The orthogonal natures of all side- and main-chain self-assembly events were demonstrated by (1)H NMR spectroscopy and isothermal titration calorimetry. The resulting fully functionalized block copolymers are the first copolymers combining both side- and main-chain self-assembly, thereby providing a high degree of control over copolymer functionalization and architecture and bringing synthetic materials one step closer to the dynamic self-assembly structures found in nature.
