Two-Dimensional Tetrathienonaphthalenes-Based Donor–Acceptor Copolymers: Synthesis, Isomeric Effect, and Organic Field-Effect Transistors

Two-dimensional alkylated αβ-TTN and βα-TTN were designed and synthesized. The cross-shaped αβ-TTN and βα-TTN moieties were polymerized to afford two isomeric polymers, Pαβ-TTNFBT40 and Pβα-TTNFBT4...
