Block Copolymer Nanotubes.
Rigid cylindrical micelles are made from polyisoprene-block-poly(2-cinnamoylethyl methacrylate)-block-poly(tert-butyl acrylate). The PI-PCEMA-PtBA polymer assembles to micelles with PI as the core, PCEMA as the shell, and PtBA as the corona. The cylindrical structure is fixed by photocrosslinking the PCEMA shell, and PCEMA-PtBA nanotubes are obtained by degrading the PI core with ozone (see scheme).
