“…These holes participate in a Fenton-like CuI/CuII redox reaction, which efficiently produces • OH radicals, further facilitating the degradation of dyes, as shown in Figure 6. 17 To confirm the role of • OH radicals in the dye degradation mechanism, scavenger tests (radical trapping experiments) were performed for both the polymers. Specifically, isopropanol (IPA), disodium EDTA (Na 2 EDTA), and benzoquinone (BQ) were selected as scavengers capable of capturing hydroxyl radicals ( • OH), holes (h + ), and superoxide radicals ( • O 2 − ), respectively.…”

“…Adsorption and chemical and biological oxidation are some techniques that have been used to remove organic dyes from water. However, these methods are costly as well as time-consuming. ,− To develop sustainable material/catalyst for dye degradation, one must consider cost-effectiveness, design, market viability, technology, and environmental impact of the material.…”

The utilization of cost-effective, environmentally friendly, and renewable sunlight-driven photocatalysts is a promising approach for environmental remediation. There has been growing interest in utilizing semiconducting materials for this purpose. Herein, we report, two new semiconducting 2D-coordination polymers (CPs), [Cu 4 (μ 2 -I) 2 (μ 3 -I) 2 (μ 2 -L1) 2 ] n (CP1) and [Cu 2 (μ 2 -I) 2 (μ 2 -L2) 2 ] n (CP2), achieved from the reaction of CuI and isomeric N−S donor ligands. CP1 features Cu 4 I 4 staircase secondary building units (SBUs), while CP2 possesses Cu 2 I 2 rhomboid SBUs. Both CP1 and CP2 demonstrate efficient photocatalytic activity in degrading methylene blue (MB) and rhodamine B (RHB) under sunlight. Notably, both dyes were rapidly degraded with a minimal catalyst loading. CP1 exhibits superior photocatalytic performance over CP2 because of narrower energy band gap and higher metal content, achieving a remarkable 96.75% degradation of MB in 21 min. Excellent photocatalytic performance, high stability, recyclability, and convenient synthesis make these CPs suitable for practical applications in environmental remediation.

Due to its built-up chemoresistance after prolonged usage, the demand for replacing platinum in metal-based drugs (MBD) is rising. The first MBD approved by the FDA for cancer therapy was cisplatin in 1978. Even after nearly four and a half decades of trials, there has been no significant improvement in osteosarcoma (OS) therapy. In fact, many MBD have been developed, but the chemoresistance problem raised by platinum remains unresolved. This motivates us to elucidate the possibilities of the copper and zinc (CuZn) combination to replace platinum in MBD. Thus, the anti-chemoresistance properties of CuZn and their physiological functions for OS therapy are highlighted. Herein, we summarise their chelators, main organic solvents, and ligand functions in their structures that are involved in anti-chemoresistance properties. Through this review, it is rational to discuss their ligands’ roles as biosensors in drug delivery systems. Hereafter, an in-depth understanding of their redox and photoactive function relationships is provided. The disadvantage is that the other functions of biosensors cannot be elaborated on here. As a result, this review is being developed, which is expected to intensify OS drugs with higher cure rates. Nonetheless, this advancement intends to solve the major chemoresistance obstacle towards clinical efficacy.

Two Cu(i) coordination polymers based on a new benzimidazolyl-tetrazolyl heterotopic ligand for visible-light-driven photocatalytic dye degradation

Abstract: Two Cu(I) coordination polymers (CPs), namely, [CuI(DBPT)(H2O)]n (HDBPT = 3,5-di(1H-benzeimidazol-yl)phenyl)-2H-tetrazole, CP 1) and [CuI(DBPT)·DMF] n (CP 2), were constructed based on a new N-containing heterotopic triangular ligand. CP 1 is...
