When mixtures of dislike thiolated molecules are co-assembled to form a monolayer on flat Au surfaces there is a well characterized separation in domains. A similar effect happens when these mixtures are assembled on gold nanoparticles. Using high resolution scanning tunneling microscopy images we will show that depending on the interfacial configurational entropy it is possible to achieve either stripe like domains or Janus-type arrangement. It will also be shown that thera are specific signatures of these arrangements in the NMR spectra of these particles. Structure-property relationships will be presented.
