Thiophene-S,S-dioxidized Indophenine: A Quinoid-Type Building Block with High Electron Affinity for Constructing n-Type Polymer Semiconductors with Narrow Band Gaps.

Angew. Chem. Int. Ed. 2016;55:3459-3462

This the synthesis of a thiophene-S,S-dioxidized indophenine-containing conjugated polymer PIDTOTT. This polymer exhibits unipolar n-type semiconductor characteristics with exceptionally high electron mobility (up to 0.14 cm2 V–1 s–1).

Compound 2 is oxidized without separation of the six isomers (2a–f). The resulting three isomers (3a–c) could convert into the most stable isomer 3a by heating at 110 °C. This study provides an efficient way of making conjugated polymers with high electron affinity.
