From catalyst design to molecular devices : theory and experiments.

摘要: Three different topics are presented herein. With the help of molecular-orbital analysis, unique geometry and catalytic properties d0 bent-metallocenes was analyzed in search for cyclopentadienyl substitutes. To overcome inherent racemization coordinatively unsaturated piano-stool complexes, a ten-electron donor ligand designed. This incorporates an arene bearing two tethers: phosphine imine (abbreviated PArN). It shown that upon η 6:η 1:η 1-coordination PArN to ruthenium, configurationally stable complex results [Ru(η 1-PArN)L] n+. A tripodal dodecadentate ligand, incorporating three soft bipyridine donors as well harder salicylamide chelates, synthesized. allowed investigation iron release from ferric enterobactin, suggesting protonation/translocation into salicylate-binding mode. In presence single ion depending on its oxidation mode, it this system displays switch-like properties.
