Conventional and synchrotron-based Mössbauer spectroscopy of photo-switchable oligonuclear com-plexes & magnetic exchange couplings in radical-bridged complexes (A04)

这个3MET项目的重点是自旋交叉（SCO） Fe -和光活性Ir中心之间的功能协同性，并研究了在氧化还原活性和光致变色桥接配体存在的情况下，利用同步加速器核正向散射（NFS）通过Mössbauer效应研究了Ir位点的光激发对Fe - SCO的影响。它还能在与Fe配合物中对Dy离子进行161Dy核非弹性散射（NIS）和NFS。它还使用传统的57Fe-Mössbauer光谱和57Fe NFS和NIS。进一步研究了三核配合物中二茂铁与氧化还原活性配体之间的光诱导电子转移，以及Fe2 SCO配合物与自由基桥接配体之间的光诱导电子转移。

This 3MET project focuses on the functional cooperativity between spin crossover (SCO) Fe - and photoac-tive Ir centers, and it investigates the optical excitation of the Ir sites influencing the Fe – SCO in the pres-ence of redox-active and photochromic bridging ligands, utilizing synchrotron-based nuclear forward scat-tering (NFS) by the Mössbauer effect of the 193Ir nucleus. It also performs 161Dy nuclear inelastic scattering (NIS) and NFS of Dy ions in complexes with Fe. It also uses conventional 57Fe-Mössbauer spectroscopy and 57Fe NFS and NIS. It further studies photo-induced electron transfer between ferrocene and redox-active ligands in trinuclear complexes, and Fe2 SCO complexes with radical bridged ligands.
