本章综述了钴-二氧杂环戊烯配合物中与价态互变异构（VT）跃迁相关的最新进展。它首先讨论了VT转变的诱导，包括热诱导、压力诱导、光诱导、磁场诱导和X射线诱导的VT转变。它还解释了其他因素，有助于VT过渡，即，辅助配体效应，抗衡和溶剂化效应，和协同性。本章最后讨论了多核VT配合物（双核VT配合物和高分子VT配合物）和双功能VT配合物。虽然晶体堆积和分子间相互作用仍然基本上超出了合成化学家的控制，但意外的发现已经提供了几种化合物，其中分子间相互作用产生的协同性已经产生了两种性质，这两种性质被认为是基于VT转变的功能分子材料所必需的。这些是具有宽滞后和非常长寿命的可访问亚稳态的室温双稳态。
This chapter reviews recent advances that relate to valence tautomeric (VT) transitions in cobalt‐dioxolene complexes. It begins with a discussion on the induction of VT transitions, including thermally induced, pressure induced, light induced, magnetic field induced, and x‐ray induced VT transitions. It also explains other factors that contribute to the VT transition, namely, ancillary ligand effects, counterion and solvation effects, and cooperativity. The chapter finally presents discussions on polynuclear VT complexes (dinuclear VT complexes and polymeric VT complexes) and bifunctional VT complexes. Although crystal packing and intermolecular interactions remain essentially beyond the control of the synthetic chemist, serendipity has afforded several compounds where cooperativity resulting from intermolecular interactions has given rise to the two properties identified as essential for functional molecular materials based on VT transitions. These are room temperature bistability with wide hysteresis and very long‐lived accessible metastable states.
