Transition metal complexes provide photofunctional properties through the charge transfer excited states of their metal ion and organic ligand components. Recently, there are increasing reports on the charge transfer excited states of the ligand (π)- and 4f-orbitals of lanthanide complexes, where the latter are shielded by filled 5s and 5p orbitals. This area of research is relatively unestablished; thus, the study of photo-excited organic-lanthanide charge transfer would lead to the construction of next-generation photofunctional metal complexes. In this review, we summarize the latest research progress in photofunctional materials using the charge transfer excited states of lanthanide complexes, and discuss the photophysical/theoretical analyses of these charge transfer excited states.
过渡金属配合物通过其金属离子和有机配体组分的电荷转移激发态提供光功能特性。最近，关于镧系配合物的配体(π)轨道和4f轨道的电荷转移激发态的报道越来越多，其中后者被充满的5s和5p轨道所屏蔽。这一研究领域相对尚未确立；因此，对光激发有机-镧系电荷转移的研究将有助于构建下一代光功能金属配合物。在这篇综述中，我们总结了利用镧系配合物的电荷转移激发态在光功能材料方面的最新研究进展，并讨论了这些电荷转移激发态的光物理/理论分析。
