We prepared a series of arylaminoanthraquinone derivatives, including those with electron-accepting sulfone units and/or with electron-donating dialkylamino units. A color-tunable anthraquinone library that reached into the NIR region could be prepared through the precise control of frontier orbitals. Fine color-tuning was achieved through proper selection and positioning of the substituents. Effective
我们制备了一系列芳基氨基蒽醌衍生物,包括那些具有受电子砜单元和/或具有给电子二烷基氨基单元的衍生物。通过对前沿轨道的精确控制,可以制备一个进入近红外区域的颜色可调的蒽醌库。通过正确选择和定位取代基来实现精细的颜色调整。给电子苯胺/对苯二胺和受电子蒽醌亚结构之间有效的分子内氢键辅助电荷转移相互作用引起了蒽醌的显着红移。取代基的数量和位置以及分子构象也显着有助于确定光物理性质。
