Novel pyrazole bipyridine ligands have been synthesized from 4,4′-substituted bipyridines through oxidation, chlorination and non-catalyzed C–N coupling of potassium pyrazolate with 6-halogen-4,4′-bipyridines in diglyme. These tridentate pyrazole–bipyridine ligands are of interest as components of new redox systems for dye-sensitized solar cells.
新的吡唑配位体联吡啶已从通过氧化,氯化和非催化C-N 4,4'-取代的联吡啶与二甘醇二甲醚6卤-4,4'-联吡啶钾吡唑特的偶联合成。这些三齿吡唑联吡啶配位体是令人感兴趣的,作为染料敏化太阳能电池的新的氧化还原体系的组分。
