A new terthiophene-based imidazole luminophore 5,5'-(1-thieno[3,4-d]imidazole-4,6-diyl)bis(thiophene-2-carboxylic acid) (TIBTCH, ) was synthesized in one step from previously reported 4,6-di(thiophen-2-yl)-1-thieno[3,4-d]imidazole (DTTI, ), and their photophysical properties were studied and compared accordingly. Under solvothermal conditions, reacting with Mn(OAc) yielded a new three-dimensional metal-organic framework (MOF, ) which was structurally defined by single-crystal X-ray diffraction. In , all Mn(II) ions octahedrally bind to carboxylate- atoms to form a linear Mn secondary building unit (SBU) that contains three distinct coordination modes. Importantly, exhibits dual functional properties of ligand-based emission and metal-based magnetic behaviors.
一种新的基于噻吩并[3,4-d]咪唑的咪唑发光体 5,5'-(1-噻吩并[3,4-d]咪唑-4,6-二基)双(噻吩-2-羧酸)（TIBTCH，）由先前报道的 4,6-二（噻吩-2-基）-1-噻吩并[3,4-d]咪唑（DTTI，）一步合成，并相应地研究和比较了它们的光物理性质。在溶剂热条件下，与 Mn(OAc)反应生成了一种新的三维金属-有机骨架（MOF，），其结构由单晶 X 射线衍射确定。在中，所有 Mn(II)离子以八面体形式与羧酸根原子配位，形成包含三种不同配位模式的线性 Mn 次级构筑单元（SBU）。重要的是，表现出配体基发射和金属基磁行为的双重功能特性。
