A series of novel beta-mercapto carbonyl compounds (3a-z), methyl 2-(3-oxo-1,3-diarylpropylthio)acetate, were synthesized and characterized via iodine-catalyzed addition of methyl thioglycolate to chalcones (1a-z).
Synthesis, characterization of novel cyclohexenone derivatives and computation of their optical response
molecules apparently emit violet light at about 406–414 nm. Moreover, polarizability ( α ) and first static hyperpolarizability ( β ) were computed by density functional theory (DFT). In addition, the UV–Vis spectra, transition character and electronic structures of these CDs were computed by using the time dependent density functional theory (TD-DFT). It was interesting to note that the values of computed
摘要 本研究报告了使用合理设计合成原理和量子化学计算成功开发了五种新的环己烯酮衍生物 (CD)。这些新的 CDs 是按照方便的 Robinson 环化路线合成的,这些 CDs 的分子结构后来通过各种分析技术如 1 H NMR、13 C NMR、FT-IR、UV-Vis 光谱和质谱法进行了确认。光谱研究的结果表明,合成的 CDs 分子明显发出大约 406-414 nm 的紫光。此外,极化率( α )和第一静态超极化率( β )通过密度泛函理论(DFT)计算。此外,紫外-可见光谱,通过使用时间相关密度泛函理论(TD-DFT)计算这些 CD 的跃迁特征和电子结构。有趣的是,计算的和实验的电子跃迁 (λ max ) 的值非常一致。最后,我们新合成的 CD 的更高非线性光学 (NLO) 响应的测量表明它们在光子器件中的应用潜力。
