Disclosed herein are embodiments of complexes exhibiting reversible light-induced magnetization switching with unprecedented lifetimes. In particular embodiments, the complexes are provided as organic thin films that can exhibit long lifetimes at ambient temperatures. In some representative embodiments, the complex comprises an electronically bistable cobalt complex functionalized with an optically bistable ligand. A photoisomerization-induced spin–charge excited state (PISCES) process can occur, resulting in the direct observation of light-induced spin state switching at room temperature in the solid state.
本文公开了一些具有前所未有的寿命的可逆光诱导磁化开关复合物的实施例。在特定的实施例中,这些复合物被提供为有机薄膜,在常温下可以展示长寿命。在一些代表性的实施例中,该复合物包括一种电子双稳态
钴配合物,其被光学双稳态
配体功能化。可以发生光异构化诱导自旋-电荷激发态(
PISCES)过程,导致在固态下直接观察到室温下光诱导自旋态转换。
