Soft Photocatalysis: Organic Polymers for Solar Fuel Production

Solar fuel generation has attracted vast research interest as an environmentally benign means of producing energy from sunlight for catering to the ever growing world energy demands. As an alternative to inorganic semiconductors, organic polymers have entered the stage as promising photocatalytic systems offering a yet unprecedented scope for molecular engineering and precise tuning of optoelectronic properties. This perspective presents an overview of the development, state-of-the-art, and growth perspectives of this emerging field and highlights recent advances in photocatalyst design with a particular focus on structure–property–activity relationships in structurally well-defined 2D polymers for hydrogen evolution.
