Syntheses, Structures, and Luminescence Properties of Two Copper(II) Complexes Constructed by Rigid Bis(triazole) and Nitrogen‐containing Carboxylic Acid Ligands

Abstract

Two new copper(II) complexes with the formulas [Cu(btb)(pydc)(H 2 O)] n (1) and [Cu(btb) 0.5 (nph)(H 2 O)] n (2) have been synthesized under hydrothermal conditions by employing a rigid bis(triazole) ligand (btb = 4,4 0 -bis (1,2,4-triazolyl-1-yl)-biphenyl) and two carboxylic acids mixed ligands (H 2 pydc = pyridine-2,5-dicarboxylic acid and H 2 nph = 3-nitrophthalic acid). The copper atoms present different environments, with a tetragonal pyramidal geometry in 1 and octahedral configuration in 2. Complex 1 displays a dinuclear cluster, which is further packed into a 2D supramolecular layer by classical O H Á Á Á O hydrogen bonds. Complex 2 possesses a trinodal 3,4,4-connected 3D framework with a rare sqc69 topology. In addition, thermal stability and luminescence property were investigated.

Coordination Polymers Based on Highly Emissive Ligands: Synthesis and Functional Properties

“…Two copper(II) coordination polymers based on btb and pyridine-2,5-dicarboxylic acid (H 2 pydc) or 3-nitrophthalic acid (H 2 nph) as co-ligands were prepared by Wang et al [136]. The btb ligand exhibited a broad emission band at 439 nm upon excitation at 380 nm.…”

Cu/CuxO@C nanocomposites as efficient electrodes for high-performance supercapacitor devices

“…Considering these factors, our attention has been focused on copper-carbon systems. Copper is one of the most common materials in electronic components due to its excellent electrical conductivity (5.7 × 10 8 S m −1 ) and low cost, [27][28][29] as are carbon-based materials such as carbon nanofibers, carbon nanotubes, graphene and so forth. [30][31][32] Most industries use the electrolysis method to refine and smelt copper, resulting in dense-state copper with an ungenerous porosity to accommodate electrolyte ions.…”
