We synthesized thiophene-fused porphyrin dimers as effective π-extended helical chromophores. The porphyrin dimers exhibit a red-shifted absorption with the edge extending up to 1100 nm, implying strong electronic communication over the two porphyrin moieties through the thiophene-fused structure. Importantly, their racemic inversion barriers can be modulated by the central metal ions.
