A recyclable type-I photosensitizer to enable red-light-driven gram-scale aerobic photocatalysis.

ABSTRACT: Developing metal-free, purely organic photocatalysts with high recyclability and the ability to utilize red light to yield specific reactive oxygen species for aerobic photocatalysis is both crucial and challenging in current research. Herein, we first found that a type-I photosensitizer, EtNBS-H, can achieve red-light-driven aerobic photocatalysis with remarkable catalytic performance and facile recoverability. Upon irradiation with red light, EtNBS-H exclusively generates O₂ ^-•, enabling the efficient hydroxylation of arylboronic acids, and oxidization of thioethers and other substrates with conversion exceeding 99%. Significantly, EtNBS-H stands out for its simple recovery and reuse through a facile pH-tunable acid-base reaction. This allows fo
