Research Abstract

We found a high-pressure induced solid-state polymerization of a thiophene derivative monomer. This finding offers a unique opportunity for obtaining highly conductive, closely packed and well-ordered organic polymer, which is crucial for the development of superconductivity. In pursuit of stable solid-sate polymerization, we prepared single crystals of an unprecedented chloro-substituted thiophene oligomer and thiophene oligomer-based charge-transfer complexes.
