Directed Organization of Platinum Nanocrystals through Organic Supramolecular Nanoporous Templates
Résumé
We propose a novel approach to trap 2 nm Pt nanocrystals using nanoporous two-dimensional supramolecular networks for cavity-confined host-guest recognition process. This will be achieved by taking advantage of two features of supramolecular self-assembly at surfaces. First, its capability to allow to the formation of complex 2D architectures, more particularly nanoporous networks, through non-covalent interactions between organic molecular building-blocks. Second, the ability of the nanopores to selectively host and immobilize a large variety of guest species. In this paper, for the first time, we will use isotropic honeycomb networks and anisotropic linear porous supramolecular networks to host 2nm Pt nanocrystals.
