Two platinum-acetylide polymers functionalized with the electron-deficient thiazolothiazole spacer are synthesized that exhibit p-channel field-effect charge transport characteristics with an impressive peak field-effect charge-carrier mobility of (2.1–2.8) × 10−2 cm2 V−1 s−1 and an on/off ratio of (0.8–1.0) × 105 for the holes. The high hole mobility value is among the highest reported for metallopolyynes to date.
