| Abstract | Mankind has now realised that its dependance on oil cannot last forever. Viable alternative fuels are frantically being sought, particularly for use in the automobile industry. Hydrogen is emerging as a promising candidate, as it can be generated from a variety of sources. As a clean burning substitute, hydrogen has the potential to dramatically cut our carbon dioxide emissions to the levels suggested in the 2007 White paper (60 % reduction by 2050), however to be practical any new fuel needs to be safe and compact. As hydrogen is a gas at ambient temperatures, it would need to be compressed under very high pressures or cooled to very low temperatures to provide sufficient supplies necessary for the running of vehicles. Neither high pressures nor low temperatures are acceptible, notleast on safety grounds. In an attempt to circumvent these problems, methods of chemical storage are been investigated. Amongst the front runners currently under investigation are microporous materials, which relie on high surface area and strong hydrogen binding affinity. Large scale syntheses and chemical flexibility are other important considerations, which put coordination networks based on metalions linked by organic spacer molecules in the shop window. These metal-organic frameworks (MOFs) have recently shown potential for hydrogen uptake with systems based on zinc clusters/carboxylate linkers exhibiting hydrogen absorption values, albeit at low temperatures, approaching the 2010targets set by the US Department of Energy for on-board hydrogen storage.It is the intention here to evaluate a promising new familiy of MOFs, the structures of which are based on zinc (or aluminium) clusters linked by diphenolate spacers. These systems possess all the attributes necessary for hydrogen absorption, can be prepared on multi-gramme scale and are readily amenable to chemical modification, including the incorporation of alkali-metal ions shown in other systems to be beneficial tohydrogen uptake. The zinc (and aluminium) clusters in our systems also possess intruiging and potentially useful conformations, which create internal pockets that are well suited to small molecule capture | |
