design, synthesis technology, and device engineering. [5,6] Therefore, PTFTs open a previously inaccessible application space in large-area, lightweight, flexible, and low-cost optoelectronics, such as logic circuits, [7,8] artificial synapses, [9] sensors, [10] light-emitting transistors, [11] and flexible display drive circuits. [12] Accordingly, display drive circuits supported by PTFTs will bring display electronics more wearable, lightweight, and even stretchable in the future and accelerate the 3D freeform and conformal display. [13,14] However, PTFTs usually show up obvious device performance deviation induced by the film anisotropy and defect during the scalable fabrication process. [15,16] This often leads to problems like circuit leakage, high power consumption, and even short circuit. Therefore, active-matrix organic lightemitting diode (AMOLED) screens based on PSCs are rarely reported. It has become an urgent problem to improve the performance uniformity of PTFT devices while ensuring device performance.The soluble property and crystallization of polymer semiconductors in the nonchlorine solvent (NClS) are important factors affecting the homogeneity of large-area films. Rigid planar framework strategies and high molecular weight strategies often lead to crystallization-dependent high mobility. However, this usually causes the problem of poor solubility. [17] Consequently, most of the "record-high mobility" performance of PSCs was at the cost of poor NClS processing ability and bad performance consistency. [18] Polar side-chain strategy [19] and random copolymerization strategy [20] can effectively improve the solubility of polymer semiconductors. However, it usually leads to complicated synthetic steps, which are not conducive to batch stability. Different from the poor NClS processability of the semicrystalline polymers, short-range ordered interconnected near-amorphous polymers, such as indacenodithiophene-co-benzothiadiazole (IDT-BT), usually exhibited considerable solubility in many NClSs. [21] These polymer semiconductors have more potential in scalable NClS processed devices and the corresponding active circuits. [22,23] Considering the molecular weight-dependent solubility and mobility characteristics of this kind of material, [24] it is reasonable to control a modest molecular weight to balance mobility and solubility.The solution-handling characteristics of π-conjugated polymer semiconductors make them promising candidates for low-cost flexible electronics. Although homogeneous and stable nonchlorine solvent (NClS) processing is the only way that must be passed for future application, polymer semiconductors still meet the challenges of poor solubility and inhomogeneities in NClS. Here, the authors primp polymer molecules with protonic acid by multiple interactions, that is, proton exchange and hydrogen bond interaction, to achieve scale and model-constrained PDVT-10c assembly in NClS. As a result, a uniform near-amorphous PDVT-C10c film is developed for polymer thinfilm transistor (PTFT) arr...
