Effect of anchoring groups on N-annulated perylene-based sensitizers for dye-sensitized solar cells and photocatalytic H2 evolution

Two new perylene dyes (YFT-1 and YFT-2) were synthesized, in which YFT-1-based DSCs showed a higher conversion efficiency of 7.58% and YFT-2 sensitized Pt/TiO2 photocatalysts displayed a higher rate of H2 evolution of 83.5 μmol h−1 under visible-light irradiation (420 nm <λ < 780 nm). Importantly, photocatalysts based on the two sensitizers exhibited good photocatalytic activity under long-term illumination.207
