Charge transport: Lastly, in an ideal photocatalytic process, it is beneficial to have mobile charge carriers, which could help prevent charge recombination and promote faster migration to the catalytic active sites. Generally, in a band-like transport with highly dispersive bands, charge carrier mobilities are higher at lower temperatures than hopping mechanisms. However, in most MOFs, hopping mechanisms are predominant. We can take inspiration from conductive MOFs to design more mobile charge carriers. MOFs with high conductivity often display enhanced charge delocalization and/or continuous charge transport pathways. The latter can be tuned by choosing linkers that tend to form π -π stacking, whereas the former can be achieved by selecting softer, more electropositive linkers and/or continuous SBUs (such as 1D metal nodes) where metals and ligands have matching energy levels and good orbital overlap. This is often a trade-off with charge separation. As an example, linkers containing thiophene groups and N atoms coordinating the metals were chosen (ol31, see Figure ).
