A pillar[5]arene pendant polymer was synthesized by ring-opening metathesis polymerization using the Grubbs first-generation catalyst and cross-linked using a bis(imidazolium) cross-linker via host–guest complexation. Inclusion of the bis(imidazolium) guest within the cavity of the pillar[5]arene resulted in the formation of a supramolecular polymer network (SPN) at high concentration. Upon high dilution, the SPN formed single-chain polymer nanoparticles (SCPNs). The formation of the SPN and SCPNs were evidenced by NMR spectroscopy, dynamic light scattering, scanning electron microscopy, and atomic force microscopy.

支柱[5]芳烃侧链聚合物通过客体-客体络合形成超分子聚合物网络和单链聚合物纳米颗粒

支柱[5]芳烃侧基聚合物是通过使用第一代格鲁布斯催化剂开环易位聚合而合成的，并使用双（咪唑鎓）交联剂通过主体-客体络合而交联。在柱[5]芳烃的空腔中包含双（咪唑）客体导致高浓度的超分子聚合物网络（SPN）的形成。在高度稀释后，SPN形成单链聚合物纳米颗粒（SCPN）。SPN和SCPN的形成通过NMR光谱，动态光散射，扫描电子显微镜和原子力显微镜证明。
