Formändernde Partikel mit räumlich kontrollierter innerer Morphologie, Anisotropie und Responsivität sind in einem einzigen kolloidalen System zugänglich. C. J. Hawker et al. nutzen in ihrer Zuschrift auf S. 7138 ff. die hierarchische Selbstorganisation von Mischungen aus Polystyrol‐b‐poly(2‐vinylpyridin)‐Blockcopolymeren und einem Tensid, um polymerbasierte Nanopartikel mit dynamisch einstellbarer...
We herein report a new facile strategy to ellipsoidal block copolymer nanoparticles that exhibit a pH‐triggered anistropic swelling profile. In a first step, elongated particles with an axially stacked lamellae structure are selectively prepared by utilizing functional surfactants to control the phase separation of symmetric polystyrene‐b‐poly(2‐vinylpyridine) (PS‐b‐P2VP) in dispersed droplets. In...
