(i.e., comb‐like) polymers bearing guanine, cytosine, uracil, or thymine moieties at the bristle ends. The polymers were stable up to 220 °C and were readily solution‐processable, yielding high‐quality films. Interestingly, the brush polymers favorably self‐assembled to form molecular multibilayer structures stabilized by hydrogen bonding interactions among the nucleobase moieties at the bristle ends
我们合成了在刷毛末端带有鸟嘌呤,胞嘧啶,尿嘧啶或胸腺嘧啶部分的化学定义明确的刷状(即梳状)聚合物。该聚合物在高达220°C的温度下稳定,并且易于固溶处理,从而制得高质量的薄膜。有趣的是,刷状聚合物有利地自组装形成分子多层结构,该结构由鬃毛末端的核碱基部分之间的氢键相互作用稳定化,从而提供了富核碱基的表面。多层结构的聚合物薄膜显示出很高的水亲和力。他们还表现出选择性蛋白吸附,抑制细菌粘附,促进细胞粘附并在小鼠中表现出良好的生物相容性。刷状聚合物类似DNA的梳状聚合物适用于生物材料和蛋白质分离应用。©2015 Wiley期刊,公司J.Polym。科学,A部分:Polym。化学2015年,53,1151至1160年
