Abstract

Abstract : We investigated the metalation and coordination reactions of Co with 2 H -5, 15-bis( para -cyanophenyl)-10, 20-bisphenylporphyrin (2 Htrans DCNPP) on a Ag(111) surface by scanning tunneling microscopy. Abstract : We investigated the metalation and coordination reactions of Co with 2 H -5, 15-bis( para -cyanophenyl)-10, 20-bisphenylporphyrin (2 Htrans DCNPP) on a Ag(111) surface by scanning tunneling microscopy. At room temperature (RT), 2 Htrans DCNPPs self-assemble into a supramolecular structure stabilized by intermolecular hydrogen bonding. The metalation of 2 Htrans DCNPP is achieved either by depositing Co atoms onto the supramolecular structure at RT, or, alternatively, by depositing the molecules onto a submonolayer Co-precovered Ag(111) surface with a subsequent heating to 500 K. In addition, the molecules coordinate to Co atoms through the N atoms in the peripheral cyano groups with a preference of isolated 4-fold coordination motifs at RT.
