The photophysical and photochemical properties of transition metal complexes have attracted considerable attention because of their recent applications as photocatalysts in artificial photosynthesis and organic synthesis, as light emitters in electroluminescent (EL) devices, and as dyes in solar cells. The general control methods cannot be always used to obtain transition metal complexes with photochemical properties that are suitable for the above-mentioned applications. In the fields of solar energy conversion, strong metal-to-ligand charge-transfer (MLCT) absorption of redox photosensitizers and/or photocatalysts in the visible region with long wavelength is essential. However, the usual methods, i.e., introduction of electron-withdrawing groups into the electron-accepting ligand and/or weak-field ligands into the central metal, have several drawbacks, including shorter excited-state lifetime, lower emission efficiency, and lower oxidation and reduction power.

Re（I）二亚胺配合物的光物理，光化学和电化学性质的调制通过配位体相互作用。

过渡金属配合物的光物理和光化学性质已引起人们的广泛关注，因为它们最近在人工光合作用和有机合成中用作光催化剂，在电致发光（EL）器件中用作发光体，并在太阳能电池中用作染料。通用控制方法不能总是用于获得具有适合上述应用的光化学性质的过渡金属配合物。在太阳能转换领域，氧化还原光敏剂和/或光催化剂在长波长可见光区域的强金属到配体电荷转移（MLCT）吸收是必不可少的。但是，通常的方法，即将吸电子基团引入电子接受配体和/或将弱场配体引入中心金属，
