transition metal ions. Crystal structures of M-1 to M-4 revealed a variety of N H⋯O, C H⋯O, C H⋯π and π⋯π interactions. Minor variations in such interactions by chemical stimuli such as metal ions, results in change in color that can be visualized by naked eyes. It has been shown that electronic structure and 1 H NMR, vibrational as well as electronic spectra from the density functional theory agree well with
摘要 维生素 K3 衍生物 2-methyl-3-[(pyridin-2-ylmethyl)-amino]-1,4-naphthoquinone (M-1), 2-methyl-3-[(pyridin-2-ylethyl)-amino ]-1,4-萘醌 (M-2), 2-methyl-3-((2-(thiophen-2-yl)methyl)amino)naphthalene-1,4-dione (M-3) 和 2-methyl -3-((2-(thiophen-2-yl)ethyl)amino)naphthalene-1,4-dione (M-4) 已经合成、表征和研究了它们对过渡金属离子的化学传感器能力。M-1 到 M-4 的晶体结构揭示了多种 NH⋯O、CH⋯O、CH⋯π 和 π⋯π 相互作用。金属离子等化学刺激引起的这种相互作用的微小变化会导致肉眼可见的颜色变化。已经表明,来自密度泛函理论的电子结构和
