Kurzfassung englisch:
Since a decade we work on mono- and polynuclear Fe(II) complexes using 1-functionalized tetrazoles aiming for spin crossover compounds for possible technological applications in information technologies and devices. Recent studies on alternative reaction pathways for the ligand synthesis yielded a microwave approach allowing for so far not accessible ligands in the homologue series of alpha,omega-ditetrazolyl alkanes or halogenated alkyl-tetrazoles. Despite giving additional insight into structure - property relationships these new Fe(II) spin crossover compounds proof the concept (e.g. terminal side-chain halogenation) to upshift the spin transition temperature.
Parallel to the above-mentioned compounds also silylated tetrazoles were synthesized yielding the first tetrazole-based Fe(II) spin crossover compounds featuring thermal spin transition above room temperature.
Synthetic aspects, structural, spectroscopic and magnetic characterisations will be presented.
