Long-Range Alignments of Single Fullerenes by Site-Selective Inclusion into a Double-Cavity 2D Open Network

摘要

Multicomponent supramolecular 2D networks are attracting considerable interest as highly ordered functional materials for applications in nanotechnology and organic electronic devices. The challenge consists in controlling the ordering of two or more molecular species into specific architectures over an extended length scale with molecular precision. Highly organized supramolecular arrays can be obtained by self-assembly of complementary molecules which can interlock via intermolecular interactions such as hydrogen bonds. An alternative approach aimed at tailoring multicomponent 2D networks consists of trapping guest molecules into a host open network to form guest-host architectures. These networks can be produced on various metallic surfaces in either ambient or UHV conditions and are usually stable at room temperature.
