Abstract
The ligand exchange chemistry for the iron-molybdenum nanocluster [H2PMo12O40⊂H4Mo72Fe30(O2CMe)15O254(H2O)98-x(EtOH)x], {Mo72Fe30(Mo12P)}-EtOH, with 3,5-lutidene, 3-butylpyridine, octanol, octanoic acid, 1-hexadecanethiol, tetraethylene glycol, and dodecylbenzenesulfonic acid is reported. The structure of {Mo72Fe30(Mo12P)} is preserved throughout the reaction and TGA analysis indicates between 5 and 15 ligands could be attached per {Mo72Fe30(Mo12P)}. AFM height measurements increase with increased ligand length; however, the apparent particle diameter appears to be smaller than expected as the ligands increase in size consistent with the adopting a non-extended conformation in a similar manner to that observed for self-assembled monolayers.
