Abstract

Toward complete artificial photosynthesis systems to generate hydrogen and oxygen using visible light and water, oxygen‐generating gel systems are designed and fabricated using the electrostatic interactions of ionic functional groups and steric effects of a polymer network. By using a graft polymer chain with Ru(bpy)~3~^2+^ units as sensitizers to closely arrange RuO~2~ nanoparticles as catalyst, the functional groups transmit multiple electrons cooperatively to generate oxygen. In this paper, a novel strategy is shown to design a hierarchical network structure using colloidal nanoparticles and macromonomers. Such a soft material to oxidize water inside a hydrogel is useful as a solar‐energy converting system.

## Abstract ## Background and Objective Light in the visible and near infrared region stimulates various cellular processes, and thus has been used for therapeutic purposes. One of the proposed mechanisms is based on cellular production of reactive oxygen species (ROS) in response to illumination.
