摘要:	我們成功的利用imine ligands來取代傳統釕金屬染料的bipyridineligand，合成了兩個新穎的染料IM101與IM104以應用在染料敏化太陽能電池上，並偵測其光電物理性質。目前應用在染料敏化太陽能電池的染料大多都以N3為模板來進行修飾，而我們引進亞胺來取代N3上的bipyridineligand，以亞胺為ancillary ligands的新型釕金屬染料，其UV吸收光譜和N719相比之下，表現出較高的吸收度且有較紅位移的表現。染料IM101與IM104成功的被合成並且具有好的光電性質表現，期望此類型染料可以具有很好的光電轉換效率並且開啟設計新一代染料設計的無限可能性。Two new imine-based ruthenium sensitizers, coded as IM104 and IM101, inwhich one or two bipyridine ligand in the traditional ruthenium complexesreplaced by the imine ligands, respectively, have been synthesized, characterizedand studied their photo-physical properties for dye-sensitized solar cellapplications. The electronic properties of these new dyes were characterized bycombining UV-vis spectroscopy and electrochemical techniques. Incorporatingimine moiety as ancillary ligands in ruthenium complexes serves as theconsiderable electronic coupling between the imine ligand and ruthenium metal.Hence, both dyes displayed a remarkably high molar extinction coefficientarising from red-shift of their metal-to-ligand charge transfer band whencompared to a commonly used N719 sensitizer. The results reported hereinprovide important synthetic advances for our broader goal of developingimine-based ruthenium complexes for light-harvesting applications. Further, thepresent work will open the infinite possibilities to design the dyes for the nextgeneration.
