摘要：
A novel class of organic dyes containing pyrenoimidazole donors, cyanoacryllc acid acceptors, and ollgothiophene pi-linkers has been synthesized and characterized. The electro-optical properties of these dyes can be tuned by changing the conjugation length of the pi-linkers. A dye containing terthiophene in the conjugation pathway exhibited a solar energy-to-electricity conversion efficiency of 5.65%.
