我们报告了开环易位聚合(ROMP)及其随后的功能化和基于非共价相互作用的嵌段共聚物的形成,合成了远螯聚(降冰片烯)和聚(环辛烯)均聚物。而所有的聚(降冰片烯)在聚合物侧链上都包含金属配合物或氢键部分,并且在聚合物链的一个末端还带有一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ABA嵌段共聚物。所有侧链和主链自组装事件的正交性质均由1证明1 H NMR光谱和等温滴定量热法。最终得到的全功能化嵌段共聚物是首个结合侧链和主链自组装的共聚物,从而提供了对共聚物功能化和结构的高度控制,并使合成材料更接近于动态胶粘剂中发现的动态自组装结构。自然。
Block copolymers labelled with molecular recognition units and comprising a hydrophobic block and a luminescent block are presented. A method of detecting biomolecules using such block copolymers is also presented. More specifically, the block copolymers of the present invention have the following Formula (I): wherein “A” is a hydrophobic block; “B” is a luminescent block; “C” is a hydrophilic block; “D” is a molecular recognition unit; “n” and “m” are integers ranging from 1 to 75; “x” is either 0 or an integer ranging from 1 to 75; and “Y” is either 0 or 1.

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
