摘要

拉帕恰尔属1,4-萘醌族,在2号碳上有一个氢氧根,在3号碳上有一个支链烯烃,命名为3-甲基-2-丁烯基,最终命名为2-羟基-3 -(3-甲基-2-丁烯基)-1,4-萘醌。作为一种发色团,它具有近紫外吸收,这是选择配体整合光致发光镧系配合物过程中的重要特征之一。光致发光材料目前在市场上广泛应用于制版、涂料、印版、胶带、颜料等发光设备。在光伏电池、光学发光示踪剂、法医化学、荧光免疫分析等领域,所谓的dmcl(分子光转换装置)的使用正在增加。了解到对这些器件的巨大需求,研究和表征具有良好发射特性并允许其在上述类别中使用的新化合物是可行的。为此,镧系元素的使用是一个很好的建议,而发色团配体的应用,如Lapachol,旨在提供最终产品的发射增加。在目前的工作中,报告了从天然来源Ipê Roxo木材中提取Lapachol的一种新的纯化工艺,以及证明新工艺可行性的表征,此外还使用该材料作为镧系化合物的粘合剂。

EXTRACTION, PURIFICATION, AND COMBINATION OF LAPACHOL IN NOVEL EUROPIUM COMPLEX
Lapachol belongs to the group of 1,4-naphthoquinones, with the addition of a hydroxide group attached to carbon 2 and a branched alkene nomenclature 3-methyl-2-butenyl attached to carbon 3, with final nomenclature 2-hydroxy-3 -(3-methyl-2-butenyl)-1,4-naphthoquinone. As a chromophore, it exhibits near-ultraviolet absorption, one of the important characteristics in the process of choosing ligands to integrate photoluminescent lanthanide complexes. Photoluminescent materials are currently widely used in the market for making plates, paints, plates, tapes, pigments, and other luminescent equipment. The use of what are called DMCLs (Molecular Light Converting Devices) is increasing in Photovoltaic Cells, Optical Luminescent Tracers, Forensic Chemistry, Fluoroimmunoassays, and more. Knowing the great demand for these devices, it is feasible to study and characterize new compounds that have favorable emission characteristics and that allow their use in the aforementioned categories. For this, the use of lanthanides is a great proposal, and the application of a chromophore ligand, such as Lapachol, aims to provide an increase in the emission of the final product. In the present work, the extraction, a new purification process of Lapachol from its natural source, the Ipê Roxo wood, is reported, as well as the characterizations that attest to the feasibility of the new process, in addition to the use of the material as a binder in lanthanide complexes.
