ABSTRACT Two supramolecular systems were constructed based on fluorene-based π-conjugated monomers with or without spiro structures, respectively, and their self-assemble behaviour and optical properties were investigated. Concentration-dependent 1H NMR and viscosity measurements indicated a transition from cyclic or oligomeric species at low concentrations to linear supramolecular polymers at high concentrations in the system without spiro structures. In contrast, the formation of cyclic species is minimised and not observed in the system with spiro structures. Graphical Abstract

取代基对芴基线性超分子聚合反应的影响

摘要 基于芴基π共轭单体分别构建了两个超分子体系，分别具有或不具有螺结构，并研究了它们的自组装行为和光学性质。浓度相关的 1 H NMR 和粘度测量表明，在没有螺结构的系统中，从低浓度的环状或低聚物质向高浓度的线性超分子聚合物转变。相比之下，环状物质的形成被最小化，并且在具有螺结构的系统中没有观察到。图形概要
