| 논문초록 | Directed self-assembly (DSA) of soft materials has been received considerable attention to produce periodic nanostructures. Among soft materials that can be controlled by DSA techniques, supramolecular structures are attractive because they have small feature size (2-10 nm), various chemical functionalities, and fast stabilization time (~mins) to self-assembly. This study demonstrates continuous and planar alignment of supramolecular structures, especially dendrimer cylinders, over large-area with DSA techniques. Planar ordering of dendrimer cylinders that have small feature size (~4.75 nm) was generated over large-area by topological patterns with high resolution (~20 nm) and high aspect ratio (＞10). According to the experimental and theoretical studies, physical surface anchoring and geometrical anchoring affected to the alignment direction of dendrimer cylinders. These approaches exhibit the significant steps to develop sub-5 nm nanostructures based on DSA of supramolecules. |
