不同大分子之间的相分离和特定的弱相互作用是许多生物系统中分子组织的基础，它们通过吸引氢键（H-键）保持在一起并通过相分离解离。我们报告的共价H-键的关联行为的显着变化相连接的聚合物链。根据聚集状态，我们观察到完整的H-键，尽管分离的阶段，或宏观相分离与大量的H-键解离。
Phase segregation between different macromolecules and specific weak interactions are the basis of molecular organization in many biological systems, which are held together by attractive hydrogen bonds (H-bonds) and dissociated by phase segregation. We report significant changes in the association behavior of covalent H-bonds by the phase of attached polymer chains. Depending on the aggregation state, we observed either intact H-bonds despite segregation of the phases, or macrophase separation with a larger amount of H-bonding dissociation.
