Polymer self-healing films containing fragments of pillar[5]arene were obtained for the first time using thiol/disulfide redox cross-linking. These films were characterized by thermogravimetric analysis and differential scanning calorimetry, FTIR spectroscopy, and electron microscopy. The films demonstrated the ability to self-heal through the action of atmospheric oxygen. Using UV-vis, 2D 1H-1H NOESY, and DOSY NMR spectroscopy, the pillar[5]arene was shown to form complexes with the antimicrobial drug moxifloxacin in a 2:1 composition (logK11 = 2.14 and logK12 = 6.20). Films containing moxifloxacin effectively reduced and biofilms formation on adhesive surfaces.
首次通过硫醇/二硫化物氧化还原交联制备了含有柱[5]芳烃片段的聚合物自愈合薄膜。这些薄膜通过热重分析、差示扫描量热法、傅里叶变换红外光谱和电子显微镜进行了表征。这些薄膜表现出通过大气氧气作用进行自愈合的能力。利用紫外可见光谱、二维氢-氢核欧沃豪斯效应光谱和扩散排序光谱，柱[5]芳烃被证明能与抗菌药物莫西沙星以2:1的组成形成配合物（logK11 = 2.14和logK12 = 6.20）。含有莫西沙星的薄膜能有效减少黏附表面上的生物膜形成。
