Metal–organic frameworks (MOFs) have attracted much interest in the fields of gas separation and storage, catalysis synthesis, nonlinear optics, sensors, luminescence, magnetism, photocatalysis gradation and crystal engineering because of their diverse properties and intriguing topologies. A Cu–MOF, namely poly[[(μ2‐succinato‐κ2O:O′){μ2‐tris[4‐(1,2,4‐triazol‐1‐yl)phenyl]amine‐κ2N:N′}copper(II)] dihydrate], {[Cu(C4H4O4)(C24H18N10)]·2H2O}n or {[Cu(suc)(ttpa)]·2H2O}n, (I), was synthesized by the hydrothermal method using tris[4‐(1,2,4‐triazol‐1‐yl)phenyl]amine (ttpa) and succinate (suc2?), and characterized by IR, powder X‐ray diffraction (PXRD), luminescence, optical band gap and valence band X‐ray photoelectron spectroscopy (VB XPS). Cu–MOF (I) shows a twofold interpenetrating 4‐coordinated three‐dimensional CdSO4 topology with point symbol {65·8}. It presents good photocatalytic degradation of methylene blue (MB) and rhodamine B (RhB) under visible‐light irradiation. A photocatalytic mechanism was proposed and confirmed. 相似文献

Coordination polymers (CPs) have been widely studied because of their diverse and adjustable topologies and wide‐ranging applications in luminescence, chemical sensors, magnetism, photocatalysis, gas adsorption and separation. In the present work, two coordination polymers, namely poly[(μ5‐benzene‐1,3,5‐tricarboxylato‐κ6O1:O1′:O3:O3:O5,O5′){μ3‐1,3‐bis[(1,2,4‐triazol‐4‐yl)methyl]benzene‐κ3N:N′:N′′}di‐μ3‐hydroxido‐dicobalt(II)], [Co2(C9H3O6)(OH)(C12H12N6)]n or [Co2(btc)(OH)(mtrb)]n, (1), and poly[[diaquabis(μ3‐benzene‐1,3,5‐tricarboxylato‐κ3O1:O3:O5)bis{μ3‐1,3‐bis[(1,2,4‐triazol‐4‐yl)methyl]benzene‐κ3N:N′:N′′}tetra‐μ3‐hydroxido‐tetracopper(II)] monohydrate], {[Cu4(C9H3O6)2(OH)2(C12H12N6)2(H2O)2]·H2O}n or {[Cu4(btc)2(OH)2(mtrb)2(H2O)2]·H2O}n, (2), were synthesized by the hydrothermal method using 1,3‐bis[(1,2,4‐triazol‐4‐yl)methyl]benzene (mtrb) and benzene‐1,3,5‐tricarboxylate (btc3?). CP (1) exhibits a (3,8)‐coordinated three‐dimensional (3D) network of the 3,8T38 topological type, with a point symbol of {4,5,6}2{42·56·616·72·82}, based on the tetranuclear hydroxide cobalt(II) cluster [Co4(μ3‐OH)2]. CP (2) shows a (3,8)‐coordinated tfz‐d topology, with a point symbol of {43}2{46·618·84}, based on the tetranuclear hydroxide copper(II) cluster [Cu4(μ3‐OH)2]. The different (3,8)‐coordinated 3D networks based on tetranuclear hydroxide–metal clusters of (1) and (2) are controlled by the different central metal ions [CoII for (1) and CuII for (2)]. The thermal stabilities and solid‐state optical diffuse‐reflection spectra were measured. The energy band gaps (Eg) obtained for (1) and (2) were 2.72 and 2.29 eV, respectively. CPs (1) and (2) exhibit good photocatalytic degradation of the organic dyes methylene blue (MB) and rhodamine B (RhB) under visible‐light irradiation. 相似文献

Two copper(II) coordination polymers, {[Cu2(btre)(hsuc)Cl(H2O)]·1.5H2O}n (1) and {[Cu2(btre)(hsuc)Br(H2O)]·1.5H2O}n (2) (btre = 1,2-bis(1,2,4-triazol-4-yl)ethane, H3hsuc = 2-hydroxysuccinic acid), were synthesized by the hydrothermal method via in situ hydroxylation reaction with fumarate (fum), btre and CuCl2/CuBr2, and characterized by elemental analyses, IR, TG and X-ray diffraction. 1 and 2 are isostructural and show a 4-connected 2-D network based on [Cu2O] dimers. 1 and 2 show good photocatalytic activity for the degradation of organic dyes methylene blue and methyl orange under UV light irradiation. 相似文献
