Die supramolekulare Assoziation von helikalen Polymeren (Polyarylacetylenen) mit einwertigen Metallkationen (Ag+, Li+ und Na+) führt zu unterschiedlichen makroskopisch chiralen Nanostrukturen, z. B. Nanokügelchen, Nanoröhren, Toroide und Gele, die eine Reihe von organischen und anorganischen Substanzen einkapseln können. Das Titelbild veranschaulicht diesen “chemischen Tornado”, der von F. Freire,...
The interaction of a highly dynamic poly(aryl acetylene) (poly‐1) with Li+, Na+, and Ag+ leads to macroscopically chiral supramolecular nanospheres, nanotubes, toroids, and gels. With Ag+, nanospheres with M helicity and tunable sizes are generated, which complement those obtained from the same polymer with divalent cations. With Li+ or Na+, poly‐1 yields chiral nanotubes, gels, or toroids with encapsulating...
