已经成功合成了一系列五种新的钌[3 + 2 + 1]配合物,编码为MC107–MC111,其中新型不对称联吡啶为辅助配体,三联吡啶三羧酸为锚定配体,并通过1 H NMR,13 C NMR和紫外可见光谱法。在可比较的条件下,与参考标准N749染料相比,观察到所有这些敏化剂的摩尔消光系数都有改善。在所有新的敏化剂中,MC108的最大太阳能转化为电转化率为5.573%(J sc = 16.81 mA cm -2,V oc= 0.50 V. FF = 0.65)在标准全球AM 1.5 G太阳条件下,与N749染料相比,效率为6.29%(J sc = 13.74 mA cm -2,V oc = 0.67 V. FF = 0.68)相似的制造和评估条件。为了了解它们的结构,电子和光物理特性,对MC107–MC111进行了密度泛函理论(DFT)和与时间有关的DFT计算。

The present invention provides substituted cyclometalated dyes with wider absorbance bands in the visible spectrum. The compounds have hexacoordinate structures as shown in formula (I) where the central transition metal (M) is bonded to two substituted bipyridine ligands and a cyclometallated 2-phenylpyridine ligand. The R groups are as defined herein. Also provided are a method of manufacturing the dyes and the use of same in electric and photoelectric devices such as dye-sensitized solar cells (DSSC), organic light-emitting diodes (OLED), field effect transistors (FET) and photoelectrochemical (PEC) cells.

Ruthenium and Co: Ruthenium(II) complexes remain prime candidates for dye‐sensitizedsolar applications; however, current ruthenium sensitizers are not compatible with cobalt(II/III) electrolytes. Herein, the effect of surface insulation on device efficiency is studied by comparing two cyclometalated tris‐heteroleptic ruthenium(II) complexes. This approach demonstrates a general principle that leads

Two novel tris‐heteroleptic Ru–dipyrrinates were prepared and tested as sensitizers in the dye‐sensitized solarcell (DSSC). Under AM 1.5 sunlight, DSSCs employing these dyes achieved power conversion efficiencies (PCEs) of 3.4 and 2.2 %, substantially exceeding the value achieved previously with a bis‐heteroleptic dye (0.75 %). As shown by electrochemical measurements and DFT calculations, the improved
