Coumarin derivatives are a class of compounds with a pronounced wide range of applications, especially in biological activities, in the medicine, pharmacology, cosmetics, coatings and food industry. Their potential applications are highly dependent on the nature of the substituents attached to their nucleus. These substituents modulate their photochemical and photophysical properties, as well as their interactions in their crystalline form, which largely determines the final field of application. Therefore, in this work a series of mono and dihydroxylated coumarin derivatives with different chemical substituents were synthesized and characterized by UV-Visible spectroscopy, thermal analysis (differential scanning calorimetry (DSC) and TGA), 1H NMR and X-Ray Diffraction to identify limitations and possibilities as a function of the molecular structure for expanding their applications in polymer science.
香豆素衍生物是一类化合物,具有广泛的应用范围,特别是在生物活性、医药、药理学、化妆品、涂料和食品工业中。它们的潜在应用高度取决于连接到它们核心的取代基的性质。这些取代基调节它们的光化学和光物理性质,以及它们在晶体形式中的相互作用,这在很大程度上决定了最终的应用领域。因此,在这项工作中,合成了一系列带有不同化学取代基的单羟基和双羟基香豆素衍生物,并通过紫外-可见光谱、热分析(差示扫描量热法(DSC)和热重分析(TGA))、1H核磁共振和X射线衍射对其进行表征,以确定根据分子结构扩展其在聚合物科学中应用的限制和可能性。
