Self-Assembly and Individual Appearance of Cobalt(II)-Tetrakisditertbutylphenylporphyrins on Ag(111)

摘要: In Sect. 5.1, the molecular arrangement and internal conformation of CoTTBPP on Ag(111) is demonstrated. Interestingly, four different arrangements were found, using routes to prepare porphyrin films. After preparation a film with coverage slightly below one monolayer by thermal sublimation, three clearly distinguishable observed. Alternatively, was prepared deposition multilayer followed subsequent annealing desorb excess molecules. Thereby, an additional, very rigid herringbone structure formed, covering most surface. The ordered phases go along conformations individual Based STM images sub-molecular resolution, models for lateral polymorphs including molecules are proposed. as extension previous works, rotation upper tert-butyl groups taken into account. derived in combination intramolecular give insight intermolecular interactions within nature phases.
