Two Triazole-Based Metal–Organic Frameworks Constructed from Nanosized Cu₂₀ and Cu₃₀ Wheels

Abstract

Two metal-organic frameworks constructed from nanosized Cu(20) and Cu(30) wheels have been obtained under hydrothermal conditions based on 1,2,3-triazole and 1-H-1,2,3-benzotriazole, respectively. Crystal structure analysis shows that their differences in the size and nuclearity of Cu(20) and Cu(30) wheels are attributed to the steric effect of ligands.

Two Series of Sandwich Frameworks Based on Two Different Kinds of Nanosized Lanthanide(III) and Copper(I) Wheel Cluster Units

“…Additionally, TM wheel often contains two or more types of bridging interaction combining supporting ligands with OH or F, such as Cr 10, 3a Fe 18 ,18 Ni 24 ,19 Cu 30 ,20 Mn 84 ,2b Mo 368 2c wheels. Therefore, TM wheel built by one kind of bridges is rare.…”

From 2-methylimidazole to 1,2,3-triazole: a topological transformation of ZIF-8 and ZIF-67 by post-synthetic modification

“…23 However, there has been only a few studies in the literature on 1,2,3-triazole-based MOFs. [24][25][26] This is because of the steric demand has an undesirable effect on metal-triazole bonds due to the vicinal arrangement of the nitrogen atoms in the 1,2,3-triazole ring. 26 To this end, Gandara et al reported six porous isostructural metaltriazolates based on 1,2,3-triazole, denoted as MET-(Mg, Mn, Fe, Co, Cu, Zn).…”

“…24 Ruan et al synthesized 1,2,3-triazole and benzotriazole metal organic frameworks from nano-sized Cu20 and Cu30. 25 Zhou et al studied two coordination polymers which consist of 1,2,3-triazole, cadmium and copper. 26 Post-synthetic modification (PSM) is a versatile modification method which can be used for the functionalization of preassembled MOFs or the formation of novel MOFs which are not attainable by de novo synthesis.…”

Isolated molybdenum-based microporous POMs for selective adsorption of gases

“…14–16 Only a few have been reported for 1,2,3-triazoles. 9,17–19 Herein, three kinds of intrinsic POM-based microporous framework materials with 1 H -1,2,3-triazoles [Mo 12 O 12 (μ 2 -O) 4 (μ 3 -O) 12 (Htrz) 4 (trz) 4 ]· n H 2 O ( n = 22, 1 ; n = 92, 2 ), [Mo 8 O 8 (μ 2 -O) 12 (Htrz) 8 ]·62H 2 O ( 4 ), and an additive [Mo 8 O 8 (μ 2 -O) 12 (Htrz) 8 ] ½ ·[Mo 12 O 12 (μ 2 -O) 4 (μ 3 -O) 12 (Htrz) 4 (trz) 4 ]·44H 2 O ( 3 ) have been obtained by premeditated pH modulations in solution. Weak alkaline conditions are more conducive to the formations of confluent microporous POM-based materials, which are different from the generic POMs formed in acidic solutions.…”

“…[14][15][16] Only a few have been reported for 1,2,3-triazoles. 9,[17][18][19] Weak alkaline conditions are more conducive to the formations of confluent microporous POM-based materials, which are different from the generic POMs formed in acidic solutions. The isolated species of POMOFs 1, 2 and 4 have been characterized by solid and solution 13 C NMR and UV-vis spectroscopies, and further investigated with gases adsorption experiments at different pressures.…”
