Layer-by-layer growth of porphyrin supramolecular thin films
View through CrossRef
Multilayer thin film growth of carboxyphenyl-substituted porphyrin on Au(111) was investigated by means of low-temperature scanning tunneling microscopy. The carboxyphenyl-substituted porphyrins are assembled into supramolecular wires on Au(111) by sequential hydrogen bonding between carboxyphenyl groups, and the dense aggregation of the supramolecular wires results in the formation of the first monolayer film. By further molecular deposition, the layer-by-layer growth of the supramolecular wires has been observed, leading to the supramolecular thin film growth.
