用扫描隧道显微镜研究了Co与2 H-5，15-双（对氰基苯基）-10，20-二苯基卟啉（2 HtransDCNPP）在Ag（111）表面的金属化和配位反应.在室温下，2 HtransDCNPPs自组装成一个超分子结构稳定的分子间氢键。2 HtransDCNPP的金属化是通过在室温下将Co原子沉积到超分子结构上，或者通过将分子沉积到亚单层Co预覆盖的Ag（111）表面上并随后加热到500 K来实现的。此外，在室温下，分子通过周围氰基中的N原子与Co原子配位，优选为孤立的4倍配位基序。
We investigated the metalation and coordination reactions of Co with 2H-5,15-bis(para-cyanophenyl)10,20-bisphenylporphyrin (2HtransDCNPP) on a Ag(111) surface by scanning tunneling microscopy. At room temperature (RT), 2HtransDCNPPs self-assemble into a supramolecular structure stabilized by intermolecular hydrogen bonding. The metalation of 2HtransDCNPP 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.
