The morphological transformation from microspheres to helical supramolecular nanofibers with controllable handedness is achieved by the introduction of molecular chirality based on amino acid derivatives (TDAP), and the chirality of the supramolecular architectures that are achieved is nullified through the coassembly of the equivalent TDAP enantiomers. The molecular detection of achiral melamine based on the R-TDAP-COOH supramolecular system is achieved by the appearance of helicity and inversion.
通过引入基于氨基酸衍生物(TDAP)的分子手性,实现了从微球到具有可控手性的螺旋超分子纳米纤维的形态转变,并且通过等量TDAP对映体的共组装使所形成的超分子结构的手性消失。基于R-TDAP-COOH超分子体系,通过螺旋性的出现和反转实现了对手性三聚氰胺的分子检测。
