中文摘要	we report a heteroleptic ruthenium complex (007) featuring the electron-rich 5-octyl-2,2'-bis(3,4-ethylenedioxythiophene) moiety conjugated with 2,2-bipyridine and exhibiting 10.7% power conversion efficiency measured at the am1.5g conditions, thanks to the enhanced light-harvesting that is closely related to photocurrent. this c107 sensitizer has an extremely high molar extinction coefficient,of 27.4 x 10(3) m-1 cm(-1) at 559 nm in comparison to its analogue c103 (20.5 x 10(3) m-1 cm(-1) at 550 nm) or z907 (12.2 x 10(3) m(-1)cm(-1) at 521 nm) with the corresponding 5-hexyl-3,4-ethylenedioxythiopliene- or nonyl-substituted bipyridyl unit. the augmentation of molar extinction coefficients and the bathochromic shift of low-energy absorption peaks along with the pi-conjugation extension are detailed by td-dft calculations. the absorptivity of mesoporous titania films grafted with z907, c103, or c107 sublinearly increases with the molar extinction coefficient of sensitizers, which is consistent with the finding derived from the surface coverage measurements that the packing density of those sensitizers decreases with the geometric enlargement of ancillary ligands.
