A new polynorbornene bearing palladated SCS pincer complexes at each repeat unit has been synthesized using ring-opening metathesis polymerization. Small mesogenic molecules possessing nitrile or pyridine-based anchoring units are instantaneously and quantitatively coordinated to the palladium center in one simple self-assembly step giving rise to a densely functionalized polymer. These results suggest that the coordination of mesogenic small molecules onto the polymer scaffold can provide a simple and efficient route to a variety of materials.
一种新型聚萘并烯的合成,具有在每个重复单元上承载的钯化SCS夹持体,采用开环复分解聚合(ROMP)法制备而成。小型介晶分子具有腈或基于吡啶的锚定单元,在一个简单的自组装步骤中即时且定量地与钯中心配位,从而形成了一种高度功能化的聚合物。这些结果表明,小型介晶分子在聚合物支架上的配位可以为各种材料提供一种简单而高效的途径。
