合成了一种用于染料敏化太阳能电池的阴离子钴-Ⅱ配合物[Co（TTT）（NCS）（3）]（-）（TTT = 4，4 '，4”-三叔丁基-2，2'：6 '，2”-三联吡啶，NCS =异硫氰酸酯）。在乙腈溶液中，Co Ⅱ配合物与固定在TiO 2薄膜上的六价阳离子敏化剂[Ru（tmam）（2）（dcb）]（6+）（tmam = 4，4 '-bis（trimethylaminomethyl）-2，2'-bipyridine，dcb = 4，4 '-（CO2 H）（2）-2，2'-bipyridine）形成离子对。离子对的可见光激发导致激发态注入，随后氧化敏化剂的快速静态再生（
An anionic Co-II complex, [Co(TTT) (NCS)(3)](-) (TTT = 4,4',4"-tri-tert-butyl-2,2':6',2"-terpyridine and NCS = isothiocyanate), was synthesized for use in dye-sensitized solar cells (DSSCs). The Co-II complex was found to ion-pair with the hexacationic sensitizer [Ru(tmam)(2)(dcb)](6+) (tmam = 4,4'-bis(trimethylaminomethyl)-2,2'-bipyridine and dcb = 4,4'-(CO2H)(2)-2,2'-bipyridine) anchored to TiO2 thin films immersed in acetonitrile solution. Visible light excitation of the ion pairs resulted in excited-state injection followed by rapid static regeneration of the oxidized sensitizer (
