Partially α-brominated derivatives of tetra-2-thienylmethane (Brn-TTM; n = 1–3) were synthesized and isolated in gram quantities. An alternative and more selective preparation of Br3-TTM was also developed. A new π-electron system based on the tetra-2-thienylmethane framework was synthesized from the monobromo derivative of tetra-2-thienylmethane.
