Heteroleptic Ru(II) complexes were designed based on 4,4′‐bis((E)‐styryl)‐2,2′‐bipyridine (bsbpy) as an ancillary ligand for dye‐sensitized solar cells (DSSCs), and those Ru(II) sensitizers, [Ru(L)(bsbpy)(NCS)2][TBA] (TBA; tetrabutylammonium), were synthesized according to a typical one‐pot reaction of [RuCl2(p‐cymene)]2 with the corresponding anchoring ligands (where L = 4,4′‐dicarboxy‐2,2′‐bipyridine
基于4,4'-bis((E)-styryl)-2,2'-bipyridine(bsbpy)作为染料敏化太阳能电池(DSSC)的辅助配体设计了杂多味Ru(II)配合物(II)增敏剂[Ru(L)(bsbpy)(NCS)2 ] [TBA](TBA;四丁基铵)是根据[RuCl 2(p- cymene)] 2与苯的典型单锅反应合成的。相应的锚定配体(其中L = 4,4'-二羧基-2,2'-联吡啶(dcbpy),4,4'-双((E)-羧基乙烯基)-2,2'-联吡啶(dcvbpy),4, 7-二羧基-1,10-菲咯啉(dcphen)或4,7-双((E)-羧基乙烯基)-1,10-菲咯啉(dcvphen))。新型Ru(II)染料[Ru(L)(bsbpy)(NCS)2] [TBA]将乙烯基间隔基掺入辅助和/或锚定配体中,相对于N719的吸收光谱,在整个UV / VIS区域显示出红移带。bsbpy辅助和dcph
