本文报道了瓜b[8]介导的偶氮苯单体超分子聚合的光控制。在溶液和固体状态下对CB[8]聚合物进行了表征。这些主客体复合物可以在高度热稳定的光稳态之间可逆地切换。此外，通过CB[8]络合实现了z -偶氮苯的显著稳定，从而允许在固体状态下进行结构表征。
Herein we report the photocontrol of cucurbit[8]uril (CB[8])-mediated supramolecular polymerization of azobenzene-containing monomers. The CB[8] polymers were characterized both in solution and in the solid state. These host guest complexes can be reversibly switched between highly thermostable photostationary states. Moreover, a remarkable stabilization of Z-azobenzene was achieved by CB[8] complexation, allowing for structural characterization in the solid state.
