Abstract
The perfect machinery of Natural Photosynthesis, powering our daily life with solar energy, is shaped by a modular network of photocomplexes, where molecular/nano-range order and distances are precisely tuned on membrane-bound compartments.1 Along these guidelines, the current frontier of Artificial Photosynthesis looks at a multi-component, interconnected system, where the cross-talk of photo-active and catalytic building blocks implements function and optimization/repair strategies.1 The expectation for man-made systems is to dissect the photosynthetic complexity and replicate its core-apparatus under a totally artificial environment, using cost-efficient synthetic strategies.2-4 In this scenario supramolecular strategies can play a crucial role to boost photo-assisted catalysis by a tailored interplay of non-covalent interactions, including hydrogen bonding, hydrophobic and electrostatic forces. Building on these concepts we report herein the functional characterization of photosynthetic nano-patterns emerging from the combination of water soluble photosensitizers with oxygenic polyoxometalates (POMs) known as the inorganic analogs of the natural PSII-OEC.5 A.
