How to substantially improve sensitizing ability of photosensitisers (PSs) through balancing its excited state lifetime and redox driving force represents a key role in promoting electron transfer efficiency and further enhancing photoconversion efficiency, however remains a great challenge. In this work, for the first time, researchers report a facile strategy to improve sensitizing ability via finely tuning the excited state of Ru(II)-PSs (Ru-1-Ru-4) for boosting CO2 photoreduction.
