From: Construction of C-C bonds via photoreductive coupling of ketones and aldehydes in the metal-organic-framework MFM-300(Cr)

a The UV-Vis diffuse reflectance spectrum of MFM-300(Cr): inset figure shows a plot for the bandgap calculation. b Mott–Schottky plot of MFM-300(Cr) at frequency of 1 kHz. c X-band EPR spectra of in situ photocatalytic reaction with 13% H2O: experimental data before and after irradiation (black), simulated spectrum (red) comprising two components: DMPO*•C(C6H5)(CH3)OH (simulation, purple) and DMPO*•OH (simulation, green). d X-band EPR spectrum of in situ photocatalytic reaction without H2O, highlighting hyperfine coupling to 14N and βH. The latter is characteristic of an adduct with a C-centred radical. e Proposed mechanism of photocatalytic synthesis of diols over MFM-300(Cr). SET = single electron transfer.
