A new organic semiconductor has been synthesized by combination of squaric acid radical anions, tetrathiafulvalene radical cations, and tetrathiafulvalene neutral molecules. Electrochemistry was utilized to oxidize the two reagents and to crystallize the material, which grew in rosettes of needles (see Figure). The semiconducting behavior is concluded to arise from interactions along the tetrathiafulvalene stacks.
