Electrochemical and spectroelectrochemical studies on platinum complexes containing 2,2′-bipyridine

Structures, Redox and Spectroscopic Properties of PdII and PtII Complexes Containing an Azo Functionality

“…195 Pt (I = 1/2) hyperfine coupling than [PtCl 2 -(bpy)] ·- [3] and [PtCl 2 (bpym)] ·-, which have very similar values. [6] The azo-based ligand pap has a much lower lying π* orbital than bpy and bpym.…”

“…Reversible reduction in such complexes is usually ligandcentered and leads to radical-anion intermediates which often show well observable 195 Pt hyperfine coupling in their EPR spectra due to sizeable metal-ligand interactions. [2][3][4][5][6] Luminescence in the solid state or in solution is another fascinating field of research related to such platinum complexes. Such luminescence, which usually occurs from metal-to-ligand charge transfer (MLCT) or intraligand πǞπ* excited states, has instigated several structure-spectroscopic correlation studies to clarify their behavior.…”

Thermal and Photoinduced Electron Transfer in Directional Bis(terpyridine)ruthenium(II)–(Bipyridine)platinum(II) Complexes

“…New bands arise at around 350 and 530 nm in the UV/Vis spectra (Figure 2, top). [49,52,53] (Figure 3). [28] Absorption spectra of This information can principally be derived from EPR spectroscopic investigations.…”

Self-Healing of Molecular Catalyst and Photosensitizer on Metal–Organic Framework: Robust Molecular System for Photocatalytic H2 Evolution from Water

“…Additionally, electron binding energy of Pt(II) 4f7/2 and 4f5/2 was very close to that of analogous MOF ( Figure S5) and Ptn_Ir_BUiO suspension showed orange to olive green color change after the beginning of photocatalysis which is known to be observed when Pt(II)-diimine type complexes are reduced ( Figure S6). 22,27 The amount of each component in Ptn_Ir_BUiO was determined by ICP-MS and 1 H NMR ( Figure S3), and field-emission scanning electron microscope (FE-SEM) showed that the size of MOF particles ranged from 50 to 200 nm ( Figure S7).
