Abstract / Description:A water-soluble metal complex dyad, Rh(III)-X-Ru(II), was incorporated in monolayers at the air/water interface by cospreading with a positively (eicosylamine) or negatively (stearic acid) charged amphiphile. After transfer of the monolayer onto a mica substrate via the Langmuir-Blodgett technique, a domain structure similar to that at the air/water interface was observed by scanning probe microscopy (SPM). With scanning force microscopy (SFM) we found domains with diameters in the µm range protruding several Å from the interstitial areas. The same structure was imaged with scanning near-field optical microscopy (SNOM) with joint registration of topographic features and ruthenium fluorescence. We present a model for the complex structure of the molecular film compatible with the different microscopy results.
