Ruthenium molecular self-assemblies

Low-dimensional ruthenium materials, built either from molecular self-assemblies, by using multidentate ligands and Ru(H20)6 or Ru2(02CR)4 polymeric building blocks, are reported. Tfre molecular self-assemblies and their derivative Ru films have been characterized by ellipsometry, FTIR-ATR, UV absorption spectroscopy, XPS,... 

There are various potential applications of photophysical phenomena in analytical chemistry. The relatively short lifetimes of most excited states, however, is a serious drawback to the construction of practical devices but studies which focus on finding ways to extend triplet lifetimes have now been described by Harriman et al. Kneas et al. have examined new types of luminescent sensor on polymer supports, and both Neurauter et al. and Marazuela et al. have designed sensors based on the ruthenium(II) polypyridine complex for the detection of carbon dioxide. A system, based on the formation of twisted intramolecular charge transfer states, has been devised for measuring the molecular weight of polymeric matrices (Al-Hassan et a/.), and the chemical reactivity at the interface of self-assembled monolayers has been assessed using fluorescence spectroscopy (Fox et al).
