In recent years, copper redox mediators have attracted growing interest in dye-sensitized solar cells (DSCs). However, experiments revealed that ubiquitously used Lewis-base additives in the electrolytes coordinate to the CuII species, which restricts further enhancement of device performance and stability. We report the application of copper complexes endowed with diamine-tripyridine pentadentate ligands, [Cu(tpe)]2+/+ (tpe=N-benzyl-N,N,N-tris(pyridin-2-ylmethyl)ethylenediamine) and [Cu(tme)]2+/+ (tme=N-benzyl-N,N,N-tris(6-methylpyridin-2-ylmethyl)ethylenediamine), as redox mediators in DSCs. Exptl. measurements demonstrate that the coordination environment of Cu(II) complexes with pentadentate ligands remains unchanged in the presence of TBP, which is in stark contrast to the state-of-the-art bipyridyl counterpart. DSCs based on [Cu(tme)]2+/+ complexes exhibit an excellent long-term stability and maintain more than 90 % of the initial efficiency after 400 h under continuous illumination, which outperform the reference devices incorporating the bipyridyl counterpart (less than 80 %) under identical conditions. In the experiment, the researchers used many compounds, for example, 6-Methyl-2-pyridinemethanol (cas: 1122-71-0HPLC of Formula: 1122-71-0).
6-Methyl-2-pyridinemethanol (cas: 1122-71-0) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O−). For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.HPLC of Formula: 1122-71-0
