Cover Story: Amphiphilic block copolymers consisting of hydrophobic regioregular chiral or achiral polythiophene chains and a hydrophilic poly(acrylic acid) chain were synthesized using a macromolecular click reaction, which formed micelles in water. The chiral polythiophene chain formed supramolecular π-stacked chiral aggregates in the micelle core that were stable in aqueous solution for long periods without precipitation. Micelles consisting of chiral and achiral copolymers showed negative nonlinear effects on supramolecular chiral aggregate formation in the core. Chiral polythiophene aggregates formed in the micelle cores were highly stabilized by the crosslinking of poly(acrylic acid) blocks with diamines in the shell. View the paper here.
