Abstract
En 中文
Hierarchical supramolecular materials assembled from achiral amphiphilic polymer micelles and chiral additives have high chiroptical activity across the visible spectrum. Kim et al. synthesized nanoscopic micelles with inner hydrophilic and outer hydrophobic blocks that hydrogen bonded to R- (or S-) mandelic acid to create nanobelts and ultimately chiral microfibers. Incorporating achiral fluorescent dyes and nanocrystals into these assemblies could produce circularly polarized emission with dissymmetry factors of about 0.1. —Phil Szuromi
