The intriguing structural properties of coordination polymers (COPs), together with the huge variety of metal ions and organic linkers to choose from, make COPs potential precursors for fabricating carbon-encapsulated metal and metal oxide nanoparticles (NPs). Herein, we have studied the role of the COP structural assembly, prepared through making subtle changes to the ligand structure, on the formation of NPs in a carbon matrix. Cu-COPs (Cu-COP-1-Cu-COP-7), generated using different amino acid-based reduced Schiff base phenolic chelating ligands, exhibited crystalline structures with differing structural organization in the solid state. Interestingly, the calcination of Cu-COP-1 and Cu-COP-5 at 330 °C produced pure CuNPs, whereas Cu-COP-2, Cu-COP-3, Cu-COP-4 and Cu-COP-7 gave CuONPs encapsulated by carbon matrix. The calcination of Cu-COP-6 produced both CuNPs and CuONPs together in the carbon matrix. The formation of CuNPs and CuONPs in the carbon matrices was unambiguously confirmed by PXRD and XPS studies. The sizes and morphologies of the Cu/CuONPs were analyzed using HR-TEM and FE-SEM. BET studies revealed higher surface areas with small pores for the CuNPs encapsulated by carbon and lower surface areas with higher porosity for the CuONP-carbon matrix. Raman spectra revealed the formation of a nitrogen-doped reduced graphene oxide (N-rGO) carbon matrix in CuNPs-1. The N-rGO coverage and high surface area with small pores provided CuNPs-1 with good stability in strong acid (10 M H2SO4). Importantly, the fabricated N-rGO-encapsulated CuNPs-1 and carbon-covered CuONPs-4 nanocomposites were used as green catalysts in solvent-free neat A3-coupling and nitroarene-reduction reactions, respectively. The products were confirmed using 1H-NMR spectra. The recovered CuNPs-1 and CuONPs-4 catalysts, after the completion of the reactions, also showed similar catalytic activity at up to five cycles, without significant loss of catalytic activity. Thus, the present studies demonstrate the influence of Cu-COP structural assembly on the formation of Cu/CuONPs as well as the carbon matrix, and open the possibility of fabricating functional nanomaterials from the vast number of available COPs with intriguing structural motifs.

Respiratory chain succinate-ubiquinone oxidoreductase (SQR or complex II) and ubihydroquinone-cytochrome (cyt) c oxidoreductase (cyt bc1 or complex III) have been demonstrated as the promising targets of numerous antibiotics and fungicides. As a continuation of our research work on the development of new fungicides, a series of 1,2,4-triazole-1,3-disulfonamide derivatives with dual functions targeting both SQR and cyt bc1 were designed and synthesized by coupling diverse diphenyl ether moieties with triazolesulfonamide units. These newly synthesized compounds were characterized by elemental analyses, 1H NMR and ESI-MS spectrometry. The in vitro assay indicated that most of the synthesized compounds displayed good inhibition against porcine succinate-cytochrome reductase (SCR) with IC50 values ranging from 3.2 to 81.8 μM, revealing much higher activity than that of the commercial control amisulbrom whose IC50 value is 93.0 μM. Further evaluation against the respective SQR and cyt bc1 indicated that most compounds exhibited SQR-inhibiting activity as well as cyt bc1-inhibiting activity, but the inhibition potency against SQR is much higher than that against cyt bc1, showing that the SCR inhibition might be contributed greatly by the SQR inhibition. The further antibacterial evaluation against Xanthomonas oryzae pv. oryzae revealed that four compounds showed excellent potency at the concentration of 20 μg mL-1. In particular, compounds 6h and 6j exhibited much better antibacterial activity than the commercial control bismerthiazol in terms of their EC50. Impressively, 6j has an EC90 of 33.62 μg mL-1, more than 10-fold higher than that of bismerthiazol.
