摘要:
Upon the one-electron reduction of N-methylquinoxalino[2,3-b]quinoxaliniums 2, neutral radicals 1 without any bulky protecting groups were generated and isolated as stable solids, which exhibit electric conductivity (sigma = 10(-7) 10(-9) S cm(-1)) as a single-component organic material due to high electrochemical amphotericity (Delta E = ca. 0.9 V).
