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

这个3MET项目主要关注自旋交叉(SCO)铁中心和光活性Ir中心之间的功能协作性，并利用193Ir核的穆斯堡尔效应，利用同步加速器核正向散射(NFS)，研究了在氧化还原活性和光致变色桥联配体存在下，影响Fe-SCO的Ir中心的光激发。它还对Dy离子与Fe形成的络合物进行了~(161)Dy核非弹性散射(NIS)和Nf~(3+)的测量。它还使用常规的57Fe-Mössbauer光谱分析和57Fe非磁谱和NIS谱。它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，以及具有自由基桥联配体的Fe2SCO配合物。

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.
