制备了锚定有三聚氰胺氢键单元的苝双酰亚胺，并检查了其与N-十二烷基氰脲酸酯（CA）结合后的超分子聚合。所得柔性超分子聚合物通过苝发色团之间的π-π堆积相互作用进行自组织，在环状烷烃中提供带状聚集体，在无环烷烃中提供绳状聚集体以形成凝胶。 【结构：见正文】
A perylene bisimide anchored with melamine hydrogen-bonding units has been prepared, and its supramolecular polymerization upon binding with N-dodecylcyanurate (CA) was examined. The resulting flexible supramolecular polymers self-organized via a pi-pi stacking interaction between perylene chromophores, affording ribbonlike aggregates in cyclic alkanes and ropelike aggregates in acyclic alkanes to form gels.
