Growth of pyromellitic dianhydride on an amino-terminated surface

Self-metalation of 2H-tetraphenylporphyrin on Cu(111): An x-ray spectroscopy study

“…84. From our data it is not possible to conclude which of the scenarios is correct, however, interdiffusion of either molecules or copper atoms seems more likely than metalation through porphyrin channels because of the rather high formation energy of Cu-TPP (ref.…”

Self-assembled monolayers of ruthenocene-substituted biphenyl ethynyl thiols on gold

“…The C 1s/Ru 3d spectrum for REBTH/Au exhibits a main C 1s spectral feature at 284.4 eV related to the biphenyl backbone and the cyclopentadienyl rings of REBTH accompanied by a weak high BE C1s shoulder, which can be deduced from a weak asymmetry of the C1s peak. The shoulder can be alternatively ascribed to the S-bonded C atom or a shake-up-like excitation in the aromatic matrix of the film [46,52,[63][64][65]. According to most recent results, the former assignment seems to be more likely [65].…”

1,10-phenanthroline metal complex covalently bonding to poly- (pyrrole-3-carboxylic acid)-coated carbon: An efficient electrocatalyst for oxygen reduction

“…2 b1), in which the pronounced peak locates at 400.4 eV can be attributed to the pyrrolic N, which is a direct indication of the polymerization of pyrrole-3-carboxylic acid on the carbon surface [23]. And, the N1s signal located at about 399.7 eV might be due to the amine & amide groups [24], which were formed when the carboxylic acid groups in polypyrrole-3-carboxylic acid were coupled with the amine groups in 5-Amine-1,10-phenanthroline molecules. The reaction between poly (pyrrole-3-carboxylic acid) and 5-Amine-1,10-phenanthroline was also be confirmed by the appearance of the pyridinic N 1s signal located at 399 eV [24].…”

Moreover, low intensity of the quaternary N 1s peak signal with the binding energy (BE) of 401.3 eV [25] can also be observed, largely due to the by-product of O-acylisourea, which was formed as the EDAC was used as the catalyst for the reaction between the carboxyl groups and the primary amines.…”
