Resumen en inglés

The development of chiral receptors for discriminating the configuration of the analyte of interest is increasingly urgent in view of monitoring the pollution in water and waste liquids. Here we investigate an easy protocol to immobilize desired non-water soluble receptors inside a water-dispersible chiral nano platform made of silica. This approach induces chirality in the receptors and at the same time makes the dye@nanohelix system dispersed in suspension of water without aggregation. We noted strong induction and amplification of chiroptical activity in both achiral or chiral (proline-based or hemicucurbituril-based) porphyrin derivatives with and without zinc ions once confined and organized in nanometric silica helices. The results clearly demonstrated that the organization-induced chirality amplification of porphyrins dominates the molecular chirality and the amplification is more efficient for more flexible porphyrins (especially free-base and achiral).< Leer menos
