The Radical Anion, Dianion and Electron Transport Properties of Tetraiodotetraazapentacene.

ABSTRACT: Tetraiodotetraazapentacene I₄ TAP, the last missing derivative in the series of halogenated silylated tetraazapentacenes, was synthesized via condensation chemistry from a TIPS-ethynylated diaminobenzothiadiazol in three steps. Single and double reduction furnished its air-stable monoanion and relatively air-stable dianion, both of which were characterized by crystallography. All three species are structurally and spectroscopically compared to non-halogenated TAP and Br₄ TAP. I₄ TAP is an n-channel material in thin-film transistors with average electron mobilities exceeding 1 cm² (Vs)^-1 .
