Abstract Aggregation can profoundly alter the excited-state properties of organic chromophores; however, crystalline supramolecular polymers are often targeted for photocatalytic conversion of solar energy due to favourable charge delocalization or exciton transport. Here we exploit aggregation as a strategy for organic chromophore rigidification to activate photocatalysis by stabilizing localized excited states.

1 Introduction Developing systems capable of generating solar fuels is becoming imperative due to the increasing global energy demand.[1] Inspired by natural photosynthesis, a viable path toward sustainable chemical productions is to design artificial processes that convert solar light into chemical energy.[2] Another point to take inspiration from natural photosynthesis is the organization of photo-functional chromophores and catalysts into light harvesting systems.[3-7] In this context, the...

1 Introduction Soft organic materials are of growing interest as biomimetic matrices to optimize the photocatalytic production of chemicals.[1] This strategy offers the integration of light harvesting structures and catalysts in materials that can internally accumulate products and be physically placed wherever needed. At the same time, materials as reactors could provide ease of separation of products and reusability of the photocatalytic matrices.
