Organic thin-film transistors (OTFTs) with ideal behavior are highly desired, because nonideal devices may overestimate the intrinsic property and yield inferior performance in applications. In reality, most polymer OTFTs reported literature do not exhibit characteristics. Supported by a structure-property relationship study of several low-disorder conjugated polymers, here, we present an empirical selection rule for candidates textbook-like high reliability factors (100% transistors). The successful should have low energetic disorder along their backbones form thin films spatially uniform landscapes. We demonstrate that these requirements satisfied semicrystalline PffBT4T-2DT, which exhibits factor (~100%) is exceptionally devices, rendering it candidate OTFT Our findings broaden semiconductors characteristics would shed light upon molecular design criteria next-generation semiconductors.
