Direct observation of copper-induced metalation of 5,15-diphenylporphyrin on Au(111) by scanning tunneling microscopy

摘要: Abstract In-situ metalation process of porphyrin molecules has been investigated by introducing guest copper atoms into porphyrins on the gold substrate in various ways. Scanning tunneling microscopy observations unambiguously demonstrate that aggregate to form islands directly surface at room temperature regardless whether this is covered molecular layer or not. Under thermal activation 363 K, these introduced can be incorporated macrocycles molecules. Based such experimental observations, a pathway for induced proposed: atom prefers enter from bottom molecule.
