The further, the better! Photoinduced charge separation between a semiconducting nanosheet donor and the acceptor methylviologen (MV 2+ ) is greatly stabilized in the presence of hectorite clay nanosheets. The distance between the donor and acceptor, which results from the formation of hectorite microdomains that selectively adsorb MV 2+ ions, is key for this stabilization (see picture).
