Nature Communications, Journal Year: 2022, Volume and Issue: 13(1)

Published: April 29, 2022

Abstract Organic semiconductors offer a tunable platform for photocatalysis, yet the more difficult exciton dissociation, compared to that in inorganic semiconductors, lowers their photocatalytic activities. In this work, we report charge carrier lifetime is dramatically prolonged by incorporating suitable donor-acceptor (β-ketene-cyano) pair into covalent organic framework nanosheet. These nanosheets show an apparent quantum efficiency up 82.6% at 450 nm using platinum as co-catalyst H 2 evolution. Charge kinetic analysis and femtosecond transient absorption spectroscopy characterizations verify these modified have intrinsically lower binding energies longer-lived carriers than corresponding without unit. This work provides model gaining insight nature of short-lived active species polymeric photocatalysts.
