Abstract

Two novel compounds, [Cu₃I₃(TPC)_0.5(BPP)₂]_n (1) and [Cu₂Cl₂(TPC)_0.5]_n (2) (TPC=1-hydroxy- 1,2,4,5-tetra(4-pyridyl)cyclohexane ligand, bpp=1,3-dipyridyl-propane ligand)have been hydrothermally synthesized and structurally characterized by elemental analyses, IR and single-crystal X-ray diffraction. Single-crystal X-ray diffraction analysis reveals that 1 and 2 are constructed by the hydrothermal in situ formation of a tetradentate ligand, TPC, through dehydrogenative coupling and hydroxylation of 1,3-bis(4-pyridyl)propane molecules. Compound 1 is three-dimensional self-penetrating network constructed in situ ligands and the original ligand which has rarely been reported in metal–organic frameworks (MOFs). Compound 2 is a chain structure with TPC. The rational design strategy in this article will facilitate the application in the construction of new MOFs or in situ ligand synthesis. Furthermore, the solid-state photoluminescent properties have also been investigated for 1 and 2. (CCDC: 1995908, 1; 2058314, 2).

摘要

两种新型化合物，[Cu ₃ I ₃ (TPC) _0.5 (BPP) ₂ ] _n (1)和 [Cu ₂ Cl ₂ (TPC) _0.5 ] _n (2) (TPC=1-hydroxy- 1,2,4, 5-四（4-吡啶基）环己烷配体，bpp=1,3-联吡啶基-丙烷配体）已被水热合成，并通过元素分析、红外和单晶 X 射线衍射对其结构进行了表征。单晶 X 射线衍射分析表明1和2是由水热原位构造的通过 1,3-双（4-吡啶基）丙烷分子的脱氢偶联和羟基化形成四齿配体 TPC。化合物1是原位配体构建的三维自穿透网络，是金属有机框架（MOFs）中鲜有报道的原始配体。化合物2为链状结构，具有TPC。本文中的合理设计策略将有助于在新型 MOFs 的构建或原位配体合成中的应用。此外，还研究了1和2的固态光致发光特性。（中央结算公司：1995908，1；2058314，2）。
