Phenothiazine‐Based D–A′–π–A Photosensitizers With Fluorine Substituent Sensitized Photocatalytic Hydrogen Evolution Under Visible Light
A series of four phenothiazine‐based D–A′–π–A organic photosensitizers was designed for photocatalytic hydrogen evolution in conjunction with Pt/TiO 2 . The molecular design strategically extends the conjugation length, thereby effectively broadening the light absorption range. The introduction of fluorine (‐F) and...
