Abstract

Two coordination polymers (CPs), [Hg(Bpbp)X₂]_n (X = Br (1), I (2), Bpbp = 4,4′-bis(4-pyridyl)-biphenyl), were synthesized via solvothermal synthesis methods, and were further fully characterized by single crystal X-ray diffraction, powder X-ray diffraction, elemental analyses, FT-IR spectroscopy, and thermogravimetric analyses. The two CPs exhibit similar one-dimensional zigzag chain structures constructed by Bpbp ligand connecting Hg(II) cations with halide ions as terminal ligands, while the zigzag chains show different configurations, symmetries and packing modes. The results of photoluminescence experiments and DFT calculations indicate that both the halide anions and conjugated Bpbp ligands show important roles in the emission process of CPs, and halide anions may tune the luminescence properties of CPs.

两种具有高效光致发光性能的卤化汞（II）配位聚合物

通过溶热合成法合成了两种配位聚合物（CPs）[Hg(Bpbp)X2]n（X = Br (1)，I (2)，Bpbp = 4,4′-双（4-吡啶基）-联苯），并进一步通过单晶 X 射线衍射、粉末 X 射线衍射、元素分析、傅立叶变换红外光谱和热重分析对其进行了全面表征。两种氯化石蜡表现出相似的一维人字链结构，由 Bpbp 配体连接 Hg（II）阳离子，卤离子作为末端配体，而人字链则表现出不同的构型、对称性和堆积模式。光致发光实验和 DFT 计算的结果表明，卤化物阴离子和共轭 Bpbp 配体在氯化石蜡的发射过程中都发挥了重要作用，卤化物阴离子可以调节氯化石蜡的发光特性。

期刊介绍： Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry. Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
