In this paper, two aggregation-induced emission (AIE) chiral fluorescent materials, S-1 and S-2, were synthesized. The materials are based on BINOL H8-BINOL backbones, respectively, large electron-absorbing groups attached to the backbones through Knoevenagel reaction. At same time, CD signals of these gradually weakened (fw increases) as they continue aggregate. However, S-2 underwent a flip-flop from negative positive signal at fw ≥ 90. And both also showed significant enantioselective recognition lysine, demonstrating their potential novel probes. Among them, fluorescence enhancement ratios (ef) for lysine 10.0 10.3, while different degrees blue shifts produced by ICT mechanism during process. addition, self-assembled morphology nanomaterials is different; comprises hollow-core vesicles that more likely aggregate form larger vesicles, whereas solid block structure. When L/D-lysine was added alone, distinctly compared S-2. With addition L-lysine, dispersed regularly spherical, with D-lysine, itself remained in aggregated vesicles. This suggests important fields optics, recognition, nanoscale self-assembly.
