2D self-assembly of phenylene-vinylene tectons at the liquid- HOPG interface: from the concentration and alkyl chains length effects to host-guest systems

Résumé

Here we report the synthesis and characterization of a series of new phenylene-vinylene tectons. The study by Scanning Tunneling Microscopy (STM) of their supramolecular self-assembly at the interface between a phenyloctane solution and Highly Oriented Pyrolytic Graphite (HOPG) demonstrates that variation of concentration and alkyl chains length led to the formation of different networks, a compact one and a nanoporous one, with a fine control of the lattice parameters. The study of host-guest properties of the nanoporous network revealed a selectivity toward guest compounds according to their shape and size.
