含有氢键和带电离子位点的无规共聚物已经通过含有离子季铵基团或2，6-二氨基吡啶官能团的异丙基苯单体的开环易位聚合合成。所有共聚物随后通过使用氢键和库仑相互作用的自组装进行官能化。研究了2，6-二氨基吡啶与N-丁基胸腺嘧啶在离子型季铵基团存在下的氢键相互作用及其与3种不同阴离子的自组装，考察了库仑相互作用对氢键强度的影响.结果发现，氢键是独立的性质和库仑相互作用的存在。这些结果证明，所研究的氢键相互作用是正交的库仑相互作用，这两种相互作用可以独立地用于彼此在同一系统中的非共价键。
Random copolymers containing both hydrogen bonding and charged ionic sites have been synthesized by the ring-opening metathesis polymerization of norbornene monomers containing either an ionic quaternary ammonium group or a 2,6-diaminopyridine functionality. All copolymers were functionalized subsequently via self-assembly using hydrogen bonding and Coulombic interactions. The hydrogen bonding interactions between 2,6-diaminopyridine and N-butylthymine were studied in the presence of the ionic quaternary ammonium group and its subsequent self-assembly with three different charged anionic species to investigate the influence of the Coulombic interactions on the strength of hydrogen bonding. It was found that hydrogen bonding was independent of the nature and presence of the Coulombic interactions. These results prove that the studied hydrogen bonding interactions are orthogonal to the Coulombic interactions and that both interactions can be used independently of each other in the same system to noncovalent...
