Abstract

A control of the interaction between two spin centers was achieved by using a mechanical motion in a terpy(Cu-salphen)2 complex. Upon coordination a conformation change and switching from a paramagnetic to an antiferromagnetically coupled system was observed by EPR and SQUID measurements.

摘要

通过在三联吡啶（铜-双水杨醛缩邻苯二胺）2配合物中利用机械运动实现了对两个自旋中心之间相互作用的控制。配位后，通过电子顺磁共振（EPR）和超导量子干涉仪（SQUID）测量观察到了构象变化以及从顺磁耦合系统到反铁磁耦合系统的转变。
