摘要:

合成了一系列含有1,5-二氧萘基仿生体系的线性供体和折叠体, 用稳态荧光光谱法定量研究了它们的临界簇集浓度(CAgC)及其影响因素. 结果显示, DX(1,4-二氧六环, Dioxane)-H2O和CH3CN-H2O二元溶剂中的簇集程度与Ф值(有机溶剂的体积分数)有关. 在DX-H2O和CH3CN-H2O体系中, 分子间与分子内π-π芳环堆积作用能促进簇集. 折叠体的分子内折叠加强了簇集程度. 线性供体的自卷曲程度随Ф值的增大而变小, 随分子中1,5-二氧萘基数目的增多而增大.

Abstract:

A series of foldamers and linear donors containing 1,5-dioxonaphthyl group were synthesized. The influence of the Critical Aggregating Concentrations(CAgCs) of the donors was detected with steady state fluorescence method. Aggregation of the donors was correspondent to the φ value of DX-H2O or CH3CN-H2O binary solvent. In DX-H2O or CH3CN-H2O binary solvent, intermolecular or intramolecular π-π stacking improved aggregation. Otherwise, intramolecular folding also enhanced aggregation. The self-coiling enlarged with decrease of the φ value and with the increased number of 1,5-dioxonaphthyl group in the molecules.

Key words: Aggregation; Foldamer; Linear donor; Self-coiling; π-π Stacking
