multifunctionalized ligands for efficient screening of sensitizers’ properties. Based on the Horner–Emmons–Wadsworth reaction, a convenient synthetic route for the extension of the π-system on 4,4′-disubstituted-2,2′-bipyridines was used to develop a novel series of functionalized 2,2′-bipyridine ligands with either electron-withdrawing or donating end-capping group. 1H NMR spectroscopy revealed that all
要探索用于染料敏化太阳能电池(DSC)的新型钌基敏化剂,就需要轻松获得多功能配体,以有效筛选敏化剂的性能。基于霍纳-埃蒙斯-沃兹沃思反应,在4,4'-双取代-2,2'-联吡啶上扩展π系统的简便合成路线被用于开发一系列新的功能化2,2'-具有吸电子或供电子封端基团的联吡啶配体。1 H NMR光谱表明,所有新的联吡啶基配体仅以其完全E异构体获得。
