Influence of anions on the synthesis of Cu(i)-based coordination polymers along with a series of derived materials for selective photocatalytic properties

Abstract

Coordination polymers (CPs) are a scientifically compelling and evolving class of highly crystalline materials. Owing to their controllable structures and morphologies, CPs can be used as a type of uniformly...

Semiconducting Copper(I) Iodide 2D-Coordination Polymers for Efficient Sunlight-Driven Photocatalysis in Dye Degradation

“…The mechanism of the photocatalytic dye degradation with the Cu­(I) framework is well established. ,,− In general, upon exposure to light, the Cu­(I) CPs absorb photons and generate electrons, possessing energies equal to or exceeding the band gap. These electrons undergo a transition from the highest occupied molecular orbitals to the lowest unoccupied molecular orbitals of the polymer, ultimately reaching the surface of (CuI) n clusters, thereby producing electron–hole pairs .…”

“…The abundant presence of copper iodide metal clusters contributes to the semiconducting nature of the synthesized CPs. Recent studies have shown that while Cu­(I) CPs are effective in degrading dyes, they have the drawback of prolonged dye degradation time and low recyclability. , The applicability of CP1 and CP2 was also explored as photocatalysts for the degradation of methylene blue (MB) and rhodamine B (RHB) under sunlight. Our compounds show excellent photocatalytic efficiency with less time and high recyclability.…”
