a Synthetic scheme: Construction of MOF-808-PBA as a donor module via post-synthetic linker exchange and then introducing methyl viologen (MV) as an electron acceptor to prepare MOF-808-PBA-MV. b HRTEM images of MOF-808. Magnified image shows the presence of micro and mesopore. c N2 adsorption isotherm of MOF-808, MOF-808-PBA, and MOF-808-PBA-MV at 77 K. d Solid-state UV–vis spectra of PBA, MV, MOF-808, MOF-808-PBA, and MOF-808-PBA-MV; inset showing the photograph of MOF-808-PBA (i) and MOF-808-PBA-MV (ii). e Photoluminescence spectra of MOF-808-PBA and MOF-808-PBA-MV. The inset shows a photograph of MOF-808-PBA and MOF-808-PBA-MV dispersed in MeOH under UV light. f Time-resolved luminescence decay of MOF-808-PBA and MOF-808-PBA-MV (λex = 330 nm, λcol = 480 nm).
