Guest-induced growth of a surface-based supramolecular bilayer. “Nature Chemistry”, vol. 3 , Issue 1, 74 - 78http://hdl.handle.net/10347/32236Self-assembly of planar molecules on a surface can result in the formation of a wide variety of close-packed or porous structures. Two-dimensional porous arrays provide host sites for trapping guest species of suitable size. Here we show that a non-planar guest species (C60) can play a more complex role by promoting the growth of a second layer of host molecules (p-terphenyl-3,5,3″,5″-tetracarboxylic acid) above and parallel to the surface so that self-assembly is extended into the third dimension. The addition of guest molecules and the formation of the second layer are co-dependent. Adding a planar guest (coronene) can displace the C60 and cause reversion to a monolayer arrangement. The system provides an example of a reversible transformation between a planar and a non-planar supramolecular network, an important step towards the controlled self-assembly of functional, three-dimensional, surface-based supramolecular architectures.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Non-planar guest moleculesSupramolecular bilayerThree-dimensional supramolecular architecturesPlanar and a non-planar supramolecular networkControlled self-assembly of functional, three-dimensional, surface-based supramolecular architectures2303 Química inorgánicajournal article10.1038/nchem.9011755-4349open access
