摘要

利用各种光谱技术制备了具有不同取代基(甲基苯基、氯苯基和硝基苯基)的新型香豆素衍生物 C1、C2 和 C3,并对其进行了表征。C1 和 C2 在 325 纳米波长处激发时会发光,而 C3 则在 335 纳米波长处有微弱的发射。利用紫外-可见吸收光谱研究了这些衍生物与过渡金属和镧阳离子的结合特性,并通过滴定法发现前者与后者形成了 ML2 复合物。每种配体与金属阳离子的螯合作用都会导致它们的发光特性发生变化。

Spectroscopic properties and stabilities of metal complexes using coumarin derivatives substituted with methyl, chloro, and nitro groups

Spectroscopic properties and stabilities of metal complexes using coumarin derivatives substituted with methyl, chloro, and nitro groups

New coumarin derivatives C1, C2, and C3 with different substituents (methylphenyl, chlorophenyl, and nitrophenyl) were prepared and characterized using various spectroscopic techniques. C1 and C2 display luminescence when excited at 325 nm, while C3 has weak emission at 335 nm. The binding properties of these derivatives toward transition metals and lanthanum cations were studied using UV-visible absorption spectroscopy, and the former cations were found to form ML2 complexes by titration method. The chelation of each ligand with metal cations induced changes in their luminescence properties.

期刊介绍: The Journal of Inclusion Phenomena and Macrocyclic Chemistry is the premier interdisciplinary publication reporting on original research into all aspects of host-guest systems. Examples of specific areas of interest are: the preparation and characterization of new hosts and new host-guest systems, especially those involving macrocyclic ligands; crystallographic, spectroscopic, thermodynamic and theoretical studies; applications in chromatography and inclusion polymerization; enzyme modelling; molecular recognition and catalysis by inclusion compounds; intercalates in biological and non-biological systems, cyclodextrin complexes and their applications in the agriculture, flavoring, food and pharmaceutical industries; synthesis, characterization and applications of zeolites. The journal publishes primarily reports of original research and preliminary communications, provided the latter represent a significant advance in the understanding of inclusion science. Critical reviews dealing with recent advances in the field are a periodic feature of the journal.
