Abstract

Two new cadmium(II) coordination polymers [Cd(HL)(H2O)]·1.5H2O (1) and [Cd(HL)(4-bpmp)0.5]·2H2O (2) (H3L = 4,4'-phosphinicobis-dibenzoic acid, and 4-bpmp = N,N'-bis(4-pyridylmethyl)piperazine) have been synthesized by self-assembly of CdCl2 with 4,4'-phosphinicobis-dibenzoate, and N,N'-bis(4-pyridylmethyl)piperazine through solvothermal/hydrothermal method. Their structures were confirmed by X-ray single crystal diffraction, infrared spectrometer (IR), and powder X-ray diffraction (PXRD) and TGA techniques. Both compounds are in Pī space group and exhibited a 2D networks constructed from dinuclear [Cd2(POO)2] or paddle-wheel [Cd2(COO)2(POO)2] units, respectively. In 2, the Cd2+ is five-coordinated and shows a rare tetragonal pyramidal geometry. At room temperature, the compounds exhibit moderately intense blue and green fluorescence emission with peaks at 381 nm and 509 nm, respectively.

组装两种发光的 4,4'-磷酸二苯甲酸镉（II）配位聚合物

两种新的镉(II)配位聚合物[Cd(HL)(H2O)]-1.5H2O (1)和[Cd(HL)(4-bpmp)0.5]-2H2O（2）（H3L = 4,4'-膦酰基二苯甲酸，4-bpmp = N,N'-双(4-吡啶基甲基)哌嗪）是由 CdCl2 与 4,4'-膦酰基二苯甲酸和 N,N'-双(4-吡啶基甲基)哌嗪通过溶热/水热法自组装合成的。通过 X 射线单晶衍射、红外光谱仪、粉末 X 射线衍射和热重分析技术确认了它们的结构。这两种化合物都属于 Pī 空间群，分别由双核 [Cd2(POO)2] 或桨轮 [Cd2(COO)2(POO)2]单元构建成二维网络。在 2 中，Cd2+ 是五配位的，并呈现出罕见的四方金字塔几何形状。室温下，这些化合物分别在 381 nm 和 509 nm 处发出中等强度的蓝色和绿色荧光。关键词：镉（II）化合物；光致发光；羧基膦酸配体 Bull.Chem.Soc.2024, 38(1), 85-98.DOI: https://dx.doi.org/10.4314/bcse.v38i1.7

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
