Twist and shout: The synthesis of polyfunctional thiophenes is reported. Quantum-mechanical calculations explain the synthetic pathway of this heterocyclization. Both experimental and computational spectral results demonstrate that the optical properties of the synthesized thiophenes are caused by the presence of an intramolecular charge-transfer (ICT) state during absorption and a twisted ICT state
