Abstract

A flexible porous network formed by the selective assembly of porphyrin derivative on Au(111) is found to be a suitable nanoscale template for accommodating large guest molecules such as C60. The supramolecular network is characterized by sequential hydrogen bonding between the carboxyphenyl groups of porphyrin derivative. It was observed that the C 60 chains are directly adsorbed on the Au(111) surface even though the supramolecular network appeared to have entirely covered this surface prior to the adsorption of C60 molecules. It was also observed that the nanopore structures were not formed before the adsorption of guest molecules. The opening of nanopores results from the subtle balancing of substrate-molecule and molecule-molecule interactions. Controlled formation of flexible porous network will allow the selective accommodation of desired guest molecules, providing a new approach for molecular recognition and selective catalysis.
