“…Yu et al synthesized a selfhealable DPP-based conjugated polymer (PDPP4T-DCM) containing dynamic covalent bonding. 189 As illustrated in Figure 26a, the coumarins in the side chains can undergo dimerization to afford a cross-linked structure under 365 nm UV irradiation, while a reverse process happens under 254 nm UV irradiation. To test the self-healing properties, a linear crack was created on the PDPP4T-DCM thin film using an AFM tip (Figure 26b).…”

Polymers are extensively exploited as active materials in a variety of electronics and energy devices because of their tailorable electrical properties, mechanical flexibility, facile processability, and they are lightweight. The polymer devices integrated with self-healing ability offer enhanced reliability, durability, and sustainability. In this Review, we provide an update on the major advancements in the applications of self-healing polymers in the devices, including energy devices, electronic components, optoelectronics, and dielectrics. The differences in fundamental mechanisms and healing strategies between mechanical fracture and electrical breakdown of polymers are underlined. The key concepts of self-healing polymer devices for repairing mechanical integrity and restoring their functions and device performance in response to mechanical and electrical damage are outlined. The advantages and limitations of the current approaches to self-healing polymer devices are systematically summarized. Challenges and future research opportunities are highlighted.

Past decades have witnessed the rapid development of conjugated polymers because of their promising semiconducting properties and applications in organic field-effect transistors (OFETs). Recent studies have shown that side-chain engineering of conjugated polymers is an efficient strategy to increase semiconducting performance. This Perspective focuses on the side-chain modulation of conjugated polymers and evaluating their effects on the performance of OFETs. The challenges and potential applications of functional highperformance OFETs through side-chain engineering are also discussed.

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. We herein present an effective strategy to boost the solubility of high‐performance polymer semiconductors in non‐halogenated solvents such as tetrahydrofuran (THF) by appending hydroxyl groups in the side chains. 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 photo‐patterned 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, we successfully utilized THF as the processing and developing solvents to achieve high density photo‐patterning with ∼82000 device arrays/cm2 for polymer semiconductors in which hydroxyl groups are appended in the side chains.This article is protected by copyright.
