“…The Shao group synthesized a copper cluster-based metal−organic framework (MOF), designated as Cu-NC, by assembling the preformed cluster Cu 6 (dmpymt) 6 with (Ph 3 P)CuI. 43 When irradiated with blue LED light at room temperature, Cu-NC successfully achieved the selective hydrogenation of the C�O bond in unsaturated carbonyl compounds 144. This process yielded a variety of primary and secondary unsaturated alcohols 145 with high efficiency.…”

Photoactive copper complexes have gained significant attention due to their photocatalytic activities. Different homogeneous Cu(I) complexes, Cu(II) complexes, and heterogeneous copper-based photocatalysts have been investigated and utilized in a broad spectrum of organic transformations. These applications span radical additions, C−C bond and C−heteroatom bond cross-couplings, aerobic oxidative reactions, and kinetic resolutions. This review summarizes the advancements in this dynamic field of visible-light-induced, excited-state coppercatalyzed organic reactions over recent years. It is organized according to the type of excited copper species involved and provides a perspective on current and future developments.

“…For example, Wang and co-workers have reported a series of isostructural Cd II -MOFs which are capable of adsorption and separation of toxic halogenated aromatics at room temperature in the liquid phase (Wang et al, 2014). Recently, Zhang and co-workers have successfully realized the photo-induced chemically selective transfer hydrogenation of unsaturated carbonyl to allyl alcohol using a cluster-based Cu I -based MOF as a bifunctional visible-light catalyst (Zhang et al, 2021). Yin and co-workers have recently reported a fluorescent sensor array composed of four lanthanide fluorescent MOF materials based on europium and terbium, which could be used for the rapid identification of some natural compounds (Yin et al, 2021).…”

Luminescent cuprous complexes are of great importance among coordination compounds due to their relative abundance, low cost and ability to display excellent luminescence. The title heteroleptic cuprous polymer solvate, catena-poly[[[(9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphane)-κ2 P,P′](μ-pyridine-3-carbonitrile-κ2 N 1:N 3)copper(I)] hexafluorophosphate dichloromethane trisolvate], {[Cu(C6H4N2)(C39H32OP2)]PF6·3CH2Cl2} n , conventionally abbreviated as {[Cu(3-PyCN)(Xantphos)]PF6·3CH2Cl2} n , where Xantphos and 3-PyCN represent (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphane) and pyridine-3-carbonitrile, respectively, has been described. In this polymer solvate, the asymmetric unit consists of three dichloromethane solvent molecules, a hexafluorophosphate anion and a polymeric heteroleptic cuprous complex cation, in which the cuprous centre is in a CuP2N2 tetrahedral coordination and is coordinated by two P atoms from the Xantphos ligand and two N atoms from two 3-PyCN ligands (the pyridyl and cyano N atoms). It is through the connection of the μ2-bridging 3-PyCN ligand that these cuprous centres are linked into a one-dimensional helical chain structure. The chains are further assembled through C—H...π interactions to form a supramolecular metal–organic framework containing solvent-accessible channels. The UV–Vis absorption and photoluminescence properties of this heteroleptic cuprous polymer have been studied on as-synthesized samples. Its luminescence emission should mainly originate from the metal-to-ligand charge transfer excited state.
