An amphoteric PQS-attached photocatalyst has been prepared that undergoes self-aggregation in water into nanomicelles. This covalently bound species enables Ir-based photoredox catalysis to be conducted in the absence of additives or co-solvents. Representative reactions are described using this new catalytic system, which require no additional investment of external energy in the form of heating or cooling. The entire aqueous reaction mixture readily undergoes in-flask recycling and thus, represents a sustainable precious metal technology.
