Here we show that the redox potential of a carbon nitride photocatalyst (CN-OA-m) can be tuned by changing the irradiation wavelength to generate electron holes with different oxidation potentials. This tuning was the key to realizing photo-chemo-enzymatic cascades that give either the (S)- or the (R)-enantiomer of phenylethanol. In combination with an unspecific peroxygenase from Agrocybe aegerita, green light irradiation of CN-OA-m led to the enantioselective hydroxylation of ethylbenzene to (R)-1-phenylethanol (99% ee). In contrast, blue light irradiation triggered the photocatalytic oxidation of ethylbenzene to acetophenone, which in turn was enantioselectively reduced with an alcohol dehydrogenase from Rhodococcus ruber to form (S)-1-phenylethanol (93% ee)."}],"publisher":"ChemRxiv","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","month":"01","doi":"10.26434/chemrxiv.13521527","date_created":"2022-09-08T11:46:45Z","author":[{"full_name":"Schmermund, Luca","last_name":"Schmermund","first_name":"Luca"},{"first_name":"Susanne","last_name":"Reischauer","full_name":"Reischauer, Susanne"},{"first_name":"Sarah","last_name":"Bierbaumer","full_name":"Bierbaumer, Sarah"},{"full_name":"Winkler, Christoph","last_name":"Winkler","first_name":"Christoph"},{"first_name":"Alba","full_name":"Diaz-Rodriguez, Alba","last_name":"Diaz-Rodriguez"},{"last_name":"Edwards","full_name":"Edwards, Lee J.","first_name":"Lee J."},{"first_name":"Selin","full_name":"Kara, Selin","last_name":"Kara"},{"last_name":"Mielke","full_name":"Mielke, Tamara","first_name":"Tamara"},{"full_name":"Cartwright, Jared","last_name":"Cartwright","first_name":"Jared"},{"last_name":"Grogan","full_name":"Grogan, Gideon","first_name":"Gideon"},{"id":"93e5e5b2-0da6-11ed-8a41-af589a024726","last_name":"Pieber","full_name":"Pieber, Bartholomäus","orcid":"0000-0001-8689-388X","first_name":"Bartholomäus"},{"full_name":"Kroutil, Wolfgang","last_name":"Kroutil","first_name":"Wolfgang"}],"type":"preprint","status":"public","citation":{"mla":"Schmermund, Luca, et al.
