Thermisch kontrollierter chiraler supramolekularer Polymorphismus in Wasser
Angewandte Chemie, EarlyView.Unter Verwendung eines amphiphilen Oligophenylenethinylen Derivats haben wir LCST‐gekoppelte Chiralität als Strategie zur Regulierung von thermoresponsivem supramolekularem Polymorphismus in Wasser etabliert. Bei Raumtemperatur bildet AggI diskrete Ansammlungen, die in der Nähe des LCST in elongierte helikale Fasern (AggII) übergehen und schlussendlich
