【 摘 要 】

Six metal-free organic dyes having thiophene (1), benzene-thiophene (2), thiophene-benzene (3), thiophene-pyridine (4), thiophene-thiophene (5), and pyridine (6) linkers between 9,9-dimethylfluorenyl terminal group and �?-cyanoacrylic acid anchor were synthesized. Among them, organic dye 5 showed the longest �?_max value (424 nm) in UV-Vis absorption spectrum, better incident monochromatic photon-to-current conversion efficiency (IPCE), highest short circuit photocurrent density (J_SC, 9.33 mA²/cm²), and highest overall conversion efficiency (�?, 3.91%).
