AbstractWe have designed and synthesized an anthracene-based zwitterion, 2-methyl-2-azoniaanthracene-7-olate. The zwitterion shows amphoteric redox properties and low-energy-light absorption originating from the small HOMO–LUMO energy gap of ca. 1.7 eV. DFT calculations show that the combination of replacing the C–H with N+–Me and introducing O− is necessary to alter the electronic structure and properties of anthracene significantly.
摘要我们设计并合成了一种基于蒽的带电离子,2-甲基-2-氮杂蒽-7-酚盐。这种带电离子展示了两性氧化还原性质和低能光吸收,来源于约1.7电子伏特的小HOMO-LUMO能隙。密度泛函理论计算表明,将C-H替换为N+–Me并引入O−的组合对显著改变蒽的电子结构和性质是必要的。
