Claims9
A photoredox catalyst, comprising:
- a poly(aryl ether) of the formula [(—Ar′—O—Ar—O—Ar″—O-)n] or [(—Ar″—O—Ar—O—Ar′—O-)n], wherein Ar comprises at least one aryl or heteroaryl group, Ar′ comprises at least one aryl or heteroaryl group, Ar″ comprises a chromophore, n is greater than 1, and the poly(aryl ether) has a BET surface area greater than 200 m2/g.
A method of photocatalysis, comprising:
- exposing a photoredox catalyst to a substrate, wherein the photoredox catalyst comprises a poly(aryl ether) of the formula [(—Ar′—O—Ar—O—Ar″—O-)n] or [(—Ar″—O—Ar—O—Ar′—O-)n], wherein Ar comprises at least one aryl or heteroaryl group, Ar′ comprises at least one aryl or heteroaryl group, Ar″ comprises a chromophore, n is greater than 1, and the poly(aryl ether) has a BET surface area greater than 200 m2/g;
- activating the photoredox catalyst;
- and
- catalyzing a reaction of the substrate.
