Abstract
A copolymer containing carbazole- and cyanovinylene-based moieties, a photoelectrode comprising a metal oxide substrate and the copolymer as a photoelectrocatalyst component to the photoelectrode, as well as a photoelectrochemical cell including the photoelectrode. Methods of producing the copolymers, and methods of using the photoelectrochemical cell to produce hydrogen gas and oxygen gas through water splitting are also provided.

- each R2 is independently selected from the group consisting of an optionally substituted alkyl, an optionally substituted cycloalkyl, an optionally substituted arylalkyl, and an optionally substituted aryl;
- each R3 is independently selected from the group consisting of a hydrogen, an optionally substituted alkyl, an optionally substituted cycloalkyl, an optionally substituted arylalkyl, an optionally substituted aryl, an optionally substituted alkoxy, an optionally substituted alkanoyl, an optionally substituted aroyl, a halogen, a nitro, and a cyano;
- each R4 is independently selected from the group consisting of a hydrogen, an optionally substituted alkyl, an optionally substituted cycloalkyl, an optionally substituted arylalkyl, an optionally substituted aryl, an optionally substituted alkoxy, an optionally substituted alkanoyl, and an optionally substituted aroyl;
- each R5 is independently selected from the group consisting of a hydrogen, an optionally substituted alkyl, an optionally substituted cycloalkyl, an optionally substituted arylalkyl, an optionally substituted aryl, an optionally substituted alkoxy, an optionally substituted alkanoyl, an optionally substituted aroyl, a halogen, a nitro, and a cyano;
