Abstract
Polymer semiconductors hold tremendous potential for applications in flexible devices, which is however hindered by the fact that they are usually processed by halogenated solvents rather than environmentally more friendly solvents. An effective strategy to boost the solubility of high-performance polymer semiconductors in nonhalogenated solvents such as tetrahydrofuran (THF) by appending hydroxyl groups in the side chains is herein presented. The results show that hydroxyl groups, which can be easily incorporated into the side chains, can significantly improve the solubility of typical p- and n-types as well as ambipolar polymer semiconductors in THF. Meanwhile, the thin films of these polymer semiconductors from the respective THF solutions show high charge mobilities. With THF as the processing and developing solvents these polymer semiconductors with hydroxyl groups in the side chains can be well photopatterned in the presence of the photo-crosslinker, and the charge mobilities of the patterned thin films are mostly maintained by comparing with those of the respective pristine thin films. Notably, THF is successfully utilized as the processing and developing solvent to achieve high-density photopatterning with ≈82 000 device arrays cm-2 for polymer semiconductors in which hydroxyl groups are appended in the side chains.

Abstract
In recent decades, polymer semiconductors, extensively employed as charge transport layers in devices like organic field-effect transistors (OFETs), have undergone thorough investigation due to their capacity for large-area solution processing, making them promising for mass production. Research efforts have been twofold: enhancing the charge mobilities of polymer semiconductors and augmenting their mechanical properties to meet the demands of flexible devices. Significant progress has been made in both realms, propelling the practical application of polymer semiconductors in flexible electronics. However, integrating excellent semiconducting and mechanical properties into a single polymer still remains a significant challenge. This review intends to introduce the design strategies and discuss the properties of high-charge mobility stretchable conjugated polymers. In addition, another key challenge faced in this cutting-edge field is maintaining stable semiconducting performance during long-term mechanical deformations. Therefore, this review also discusses the development of healable polymer semiconductors as a promising avenue to improve the lifetime of stretchable device. In conclusion, challenges and outline future research perspectives in this interdisciplinary field are highlighted.

Abstract
ConspectusIn recent decades, there has been rapid development in the field of polymer semiconductors, particularly those based on conjugated donor-acceptor (D-A) polymers exhibiting high charge mobilities. Furthermore, the application of polymer semiconductors has been successfully extended to a wide range of functional devices, including sensors, photodetectors, radio frequency identification (RFID) tags, electronic paper, skin electronics, and artificial synapses. Over the past few years, there has been a growing focus on stimuli-responsive polymer semiconductors, which have the potential to impart additional functionalities to conventional field-effect transistors, garnering increased attention within the research community. In this context, phototunable polymer semiconductors have received significant attention due to their ability to utilize light as an external stimulus, enabling remote control of device performance with high spatiotemporal resolution. Meanwhile, integration of field-effect transistors with polymer semiconductors can enable the realization of complex functions. To achieve this, precise and controllable patterning of polymer semiconductors becomes essential. In this Account, we discuss our research findings in the context of phototunable and photopatternable polymer semiconductors. These developments encompass the following key aspects: (i) polymer semiconductors, such as poly(diketopyrrolopyrrole-quaterthiophene) (PDPP4T), exhibit phototunability when blended with the photochromic compound hexaarylbiimidazole (HABI). The photo/thermal-responsive field-effect transistors (FETs) can be fabricated using blending thin films. Remarkably, these photo/thermal-responsive transistors can function as photonically programmable and thermally erasable nonvolatile memory devices. (ii) By incorporating photoswitchable groups like azo and spiropyran into the side chains of conjugated D-A polymers, we can create phototunable polymer semiconductors. The reversible isomerization of azo and spiropyran groups significantly influences the charge transport properties of these polymer semiconductors. Consequently, the performance of the resulting FETs can be reversibly tuned through UV/visible or near-infrared light (NIR) irradiation. Notably, the incorporation of two distinct azo groups into the side chains leads to polymer semiconductors with tristable semiconducting states, offering the ability to logically control device performance using light irradiation at three different wavelengths. (iii) Photopatterning of p-type, n-type, and ambipolar semiconductors featuring alkyl side chains can be achieved using a diazirine-based, four-armed photo-cross-linker (4CNN) with a loading concentration of no more than 3% (w/w). Furthermore, the semiconducting performances of FETs with patterned thin films were found to be satisfactorily uniform. Importantly, the cross-linked thin films are robust and show good resistance to organic solvents, which is useful for fabricating all-solution processable multilayer electronic devices. (iv) The introduction of azide groups into the side chains of conjugated polymers results in a single-component semiconducting photoresist. The presence of azide groups renders the side chains with photo-cross-linking ability, enabling the successful formation of uniform patterns, even as small as 5 μm, under UV light irradiation. Benefiting from the single component feature, field-effect transistors with individual patterned thin films display satisfactorily uniform performances. Moreover, this semiconducting photoresist has proven effective for efficiently photopatterning other polymer semiconductors, demonstrating its versatility.
