carrier-transport abilities, which arise from virtually identical spatial distribution of their singly
occupied and unoccupied molecular orbitals, SOMO (α) and SOMO (β), respectively. Herein,
we disclose a boron-stabilized triphenylmethyl radical that shows outstanding thermal
stability and resistance toward atmospheric conditions due to the substantial spin
delocalization. The radical is used to fabricate organic Mott-insulator transistors that operate …
