Abstract

In this work, by using a flexible tricarboxylate ligand 5-(4-carboxybenzyloxy) isophthalic acid (H₃L), a novel pillar-layered Mn–organic framework, namely, [(CH₃CH₂)₂NH₂][Mn₃(HL)L(A_C)₂] (SQNU-23, SQNU = Shangqiu Normal University), was synthesized by using a DEF/HAc solvent system. In SQNU-23, each S-shaped Mn-O chain is interconnected by two bridging modes of organic ligand to form a 3D pillar-layered framework with 1D rectangular channels. The solid-state fluorescence of SQNU-23 exhibits a significant red shift of about 140 nm compared to that of organic ligand. Moreover, SQNU-23 as a luminescent thermometer exhibits good linear dependence in the wide temperature range (100 to 300 K).

由一维s形链和柔性三羧酸盐配体构建的新型柱状层状mn -有机框架，用于宽范围温度传感

本文以柔性三羧酸配体5-（4-羧基苯氧基）间苯二甲酸（H3L）为原料，采用DEF/HAc溶剂体系合成了一种新型柱状层状锰有机骨架[(CH3CH2)2NH2][Mn3(HL)L(AC)2] （SQNU-23, SQNU =商丘师范大学）。在SQNU-23中，每个s形Mn-O链通过有机配体的两种桥接模式相互连接，形成具有一维矩形通道的三维柱状层状框架。与有机配体相比，SQNU-23的固态荧光表现出约140 nm的显著红移。此外，作为发光温度计的SQNU-23在宽温度范围（100 ~ 300 K）内表现出良好的线性依赖性。

期刊介绍： Structural Chemistry is an international forum for the publication of peer-reviewed original research papers that cover the condensed and gaseous states of matter and involve numerous techniques for the determination of structure and energetics, their results, and the conclusions derived from these studies. The journal overcomes the unnatural separation in the current literature among the areas of structure determination, energetics, and applications, as well as builds a bridge to other chemical disciplines. Ist comprehensive coverage encompasses broad discussion of results, observation of relationships among various properties, and the description and application of structure and energy information in all domains of chemistry. We welcome the broadest range of accounts of research in structural chemistry involving the discussion of methodologies and structures,experimental, theoretical, and computational, and their combinations. We encourage discussions of structural information collected for their chemicaland biological significance.
