Thin films of ruthenium phthalocyanine complexes
Ruthenium; phthalocyanine; gold; surface; laser ablation
Four new ruthenium phthalocyanine complexes bearing axial ligands with thioacetate groups that facilitate thin fi lm formation on gold surfaces are presented. Scanning tunnelling microscopy (STM) images and surface coverage data obtained by solution inductively coupled plasma mass spectrometry (ICP-MS) experiments show that peripheral and axial ligand substituents on the complexes have a signifi cant effect on their surface coverage. A laser ablation ICP-MS technique that provides information about thin films across macro-sized areas is described here for the fi rst time. Using the technique, the maximum surface coverage of a ruthenium phthalocyanine complex was found to occur within one minute of gold substrate immersion in the complexcontaining solution.
