摘　　要：A highly persistent benzoanthracenyl radical(BAR1)protected by five substituents at strategic positions is synthesized.BAR1 exhibited half-life time of 108 h in air-saturated solution,which allowed for detailed characterization in the solution.The combined experimental and theoretical study reveals the properties associated with its asymmetric structure and spin distribution.One-electron oxidation of BAR1 afforded stable cationic species BAR1+,whose structure is unambiguously determined by the NMR spectroscopy.
