Chromoselective Photocatalysis Enables Stereocomplementary Biocatalytic Pathways**

Controlling the selectivity of a chemical reaction with external stimuli is common in thermal processes, but rare visible-light photocatalysis. Here we show that redox potential carbon nitride photocatalyst (CN-OA-m) can be tuned by changing irradiation wavelength to generate electron holes different oxidation potentials. This tuning was key realizing photo-chemo-enzymatic cascades give either (S)- or (R)-enantiomer phenylethanol. In combination an unspecific peroxygenase from Agrocybe aegerita, green light CN-OA-m led enantioselective hydroxylation ethylbenzene (R)-1-phenylethanol (99 % ee). contrast, blue triggered photocatalytic acetophenone, which turn enantioselectively reduced alcohol dehydrogenase Rhodococcus ruber form (S)-1-phenylethanol (93
