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
