A supramolecularly assisted transformation of block-copolymer micelles into nanotubes.
Once around the block: Incorporation of a rigid hydrogen-bonding benzamide unit, placed at the interface between two polymer blocks, in poly(ethylene glycol) (PEG)-(thio)urea-poly(L-lactide) (PLLA) block copolymers transforms the morphology of the block copolymers, from spherical micelles, as formed by PEG-PLLA diblock copolymers, into nanotubes in solution.
