Abstract |
The mismatching phenomena are ubiquitous in complex and advanced
self-assembly, such as hierarchical assembly, macroscopic supramolecular assembly, and so
on. Recently, for macroscopic supramolecular assembly, the strategy of maximizing the
interactive surface area was used and supposed to handle this problem; however, now
there is little understanding of whether interactive surface area is the dominant factor to
guide the assembly patterns. Herein by taking millimeter cylinder building blocks with
different diameter/height (d/h) ratios as model systems, we have investigated the
interactive-surface-area-dependent assembling behaviors in macroscopic supramolecular
assembly. The results showed that the increasing d/h ratio of cylinders contributed to
selectivity of face-to-face assembled pattern over face-to-side or side-to-side geometries,
thus having improved the ordering degree of the assembled structures; however, the
mismatching phenomena could not be totally avoided due to high col
