一种新型的 CO 释放分子 M-CPones 是结合用于释放 CO 的环丙烯酮配体与过渡金属配合物的模块化支架制备的。在概念验证研究中,基于 Zn II、Fe II和 Co II的 M-CPOnes在黑暗中稳定,但通过环丙烯酮取代基和金属离子进行光触发的 CO 释放,从而可以调节光物理性质。此外,金属的选择允许使用不同的光谱方法来监测从荧光光谱到紫外/可见光谱和顺磁核磁共振光谱的光脱羰。M-CPOnes 从金属离子到环丙烯酮取代的模块化以及配体进一步功能化的潜力使得 M-CPOnes 对应用中的定制功能具有吸引力。

Exploiting the benefit of S<sub>0</sub> → T<sub>1</sub> excitation in triplet–triplet annihilation upconversion to attain large anti-stokes shifts: tuning the triplet state lifetime of a tris(2,2′-bipyridine) osmium(<scp>ii</scp>) complex
Os(II) complexes are particularly interesting for triplet–triplet annihilation (TTA) upconversion, due to the strong direct S0 → T1 photoexcitation, as in this way, energy loss is minimized and large anti-Stokes shift can be achieved for TTA upconversion. However, Os(bpy)3 has an intrinsic short T1 state lifetime (56 ns), which is detrimental for the intermolecular triplet–triplet energytransfer (TTET)

for Ru-2). The fluorescence of the Bodipyligands was almost completely quenched in Ru-1 and Ru-2. Ru-1 shows room temperature phosphorescence of the Bodipy chromophore, as well as the residual fluorescence of the Bodipyligand. Ru-2 shows only the residual fluorescence of the Bodipyligand. A long-lived Bodipy-localized triplet excited state was observed for both Ru-1 and Ru-2 upon visible light excitation

closely related complexes. The homometallic binuclear complexes, exemplified by [Ru(C2bpy-κ2-N′N-RuClCp)(PPh3)2Cp] undergo two essentially reversible oxidations, the first centered on the (C2bpy-κ2-N′N-RuClCp) moiety and the second on the Ru(C≡Cbpy)(PPh3)2Cp fragment, leading to radical cations that can be described as Class II mixed-valencecomplexes. The heterometallic binuclear complexes [Ru(C2bpy-κ

cyclopropenone-based ligands for CO release with the modular scaffold of transitionmetalcomplexes. In proof-of-concept studies, M-CPOnes based on ZnII, FeII and CoII are stable in the dark but undergo light-triggered CO release with the cyclopropenone substituents and metal ions enabling tuning of the photophysical properties. Furthermore, the choice of metal allows the use of different spectroscopic methods
