Panchromatic RuII sensitizers TF-30–TF-33 bearing a new class of 6-quinolin-8-yl-2,2′-bipyridine anchor were synthesized and tested under AM1.5 G simulated solar irradiation. Their increased π conjugation relative to that of the traditional 2,2′:6′,2′′-terpyridine-based anchor led to a remarkable improvement in absorptivity across the whole UV–Vis–NIR spectral regime. Furthermore, the introduction of a bulky tert-butyl substituent on the quinolinyl fragment not only led to an increase in the JSC value owing to the suppression of dye aggregation, but remarkably also resulted in no loss in VOC in comparison with the reference sensitizer containing a tricarboxyterpyridine anchor. The champion sensitizer in DSC devices was found to be TF-32 with a performance of JSC=19.2 mA cm−2, VOC=740 mV, FF=0.72, and η=10.19 %. This 6-quinolin-8-yl-2,2′-bipyridine anchor thus serves as a prototype for the next generation of RuII sensitizers with any tridentate ancillary.
