Visible light mediated photocatalysis by lanthanide metal-organic frameworks: enhanced specificity and mechanistic insights.

ABSTRACT: The utilization of earth-abundant photosensitizers with visible light absorption to enable sustainable photocatalysis is a long-standing challenge. Overcoming such a challenge, in this work, two lanthanide (Ln³⁺ = Tb, Eu) based metal-organic frameworks (Ln-MOFs) have been synthesized utilizing a Co³⁺-based metalloligand. Both Ln-MOFs function as remarkable photocatalysts for the selective oxidation of assorted alcohols and sulfides to their corresponding aldehydes/ketones and sulfoxides using visible light. The photophysical behavior of both Ln-MOFs and mechanism of photocatalysis is comprehensively investigated using time-resolved transient absorption spectroscopy, electrochemical impedance spectroscopy, electron paramagnetic resonance spectroscopy, photoluminescence
