The design and synthesis of ruthenium tris‐diimine photosensitizers appropriately functionalized to be (i) anchored onto transparent conductive oxides (TCO) and (ii) covalently coupled with a water‐splitting catalyst represents an important target for solar fuel production in dye‐sensitized photoelectrochemical cells (DS‐PECs). In this study, two different synthetic routes to prepare heteroleptic [Ru(4
适当地功能化为(i)固定在透明导电氧化物(TCO)上和(ii)与水分解催化剂共价偶联的钌三二亚胺光敏剂的设计与合成代表了染料敏化光电化学中太阳能燃料生产的重要目标单元(DS-PEC)。在这项研究中,评估了两种不同的制备杂合[Ru(4,4'-(CH 2 PO 3 Et 2)2 -bpy)2(N ^ N)](PF 6)2配合物的合成途径,范围和包括半夹心η有机金属途径的限制6芳烃钌络合物作为合成中间体正在得到专门研究。报道了根据第三二亚胺N ^ N配体的性质而变化的一系列新颖结构的光谱学和电化学表征。
