Applications of block copolymer self-assembly in real systems sometimes require more complicated structure including aperiodic patterns. Combining supramolecular chemistry with block copolymer self-assembly is one of strategies to overcome this problem. Block copolymer-based supramolecular systems, which were pioneered and developed by Ikkala and ten Brinke, readily use ionic interaction, hydrogen bonding, or coordination interaction to combine self-assembly of block copolymer with molecular assembly, leading to hierarchical structures with so-called “structure-within-structure” morphology on two different length scales. In this work, hierarchical assembly of block copolymer-based supramolecules in thin film was investigated and compared with that in the bulk. In addition to hierarchical structure, these systems provide an effective means to control the phase and its size of self-assembled structure and to produce nanoporous films and nano-objects. |
