In the present work, we show that by replacing, in a block copolymer, the linear polymer block with a dendronized polymer capable of participating in supramolecular interactions, the additional degree of freedom arising from the varying generation of the dendronized polymer allows engineering the self-assembly into unprecedented hierarchically ordered bulk structures. Not only does this allow control of the structures at the smaller length scale beyond current possibilities with the introduction, for example, of new columnar-rectangular, -hexagonal and -tetragonal phases, but it may also lead to new functional template materials with increased 3D topological complexity for advanced technologies.
