‘AJ.本文还详细研究了低自旋Fe11多吡啶配合物的激发态特性。1-23[Fe(Bpy)_3]~(2+)的[Fe(Bpy)_3]~(2+)络合物首先从‘a基态被光激发到单重态-金属-配体电荷转移激发态’MLCT，其中皮秒时间分辨研究30·1*表明*MLCT态在<；10ps中布居减少。通过基态漂白恢复实验，确定了[Fe(Bpy)_3]~(2+)的0.81±0.07 ns状态为38·0，并将其暂定为5T2配位场状态。在这项工作中，提出了结果，这些结果最终建立了
’Aj. The excited-state characteristics of low-spin Fe11 polypyridyl complexes have also been examinedin detail. 1 23 The [Fe (bpy) 3] 2+ complex is first photoexcited from the'A, ground state to a singlet met-al-to-ligand charge-transfer excitedstate,’MLCT, where pico-second time-resolved studies30· 1* suggest that the* MLCT state is depopulated in< 10 ps. By ground-state bleaching recovery ex-periments, a 0.81±0.07 ns state of [Fe (bpy) 3] 2+ has been identified38· 0 and tentatively assigned38 as a 5T2 ligand-field state. In this work, results are presented whichdefinitively establish the
