Abstract

Intrinsically stretchable polymer semiconductors are indispensable elements for the construction of stretchable electronic devices. Distinguished from incorporating flexible segments, developing the all-conjugated material system is expected to have great prospects. Herein, we propose the feasible atom-knotting strategy, with bridging atoms (N, C, S, and Si) partially inserted into donor units along regioregular conjugated polymer chains. The bending angle in the polymer backbone and the alkyl chain appended onto the bridging atom are central to mechanical stretchability. This strategy spawns a dual-mode stretchability enhancement mechanism. In addition to admittedly undermining film crystallinity (Mode I), bent chain conformations induced by atom-knotting could also promote bimodal stacking for preserved crystallinity and direct stretchability enhancement (Mode II). Si-knotted and S-knotted all-conjugated semiconducting polymers, initially 1.27 and 1.85 cm2V–1s–1, respectively, exhibit superior carrier mobilities, performance retention, and cyclic stability in both stretching directions. Particularly, when subjected to 100% strain or cyclic stretching under 25% strain over 1000 cycles, both could maintain over 0.95 cm2V–1s–1along the stretching direction, far higher than that of the reference conjugated polymer. Originating from the structure–property relationship, the atom-knotting strategy provides a brand-new pathway to designing high-performance intrinsically stretchable polymer semiconductors.

Abstract

Heterocycle-linked phthalocyanine-based COFs with close-packed π-π conjugated structures are a kind of material with intrinsic electrical conductivity, and they are considered to be candidates for photoelectrical devices. Previous studies have revealed their applications for energy storage, gas sensors, and field-effect transistors. However, their potential application in photodetector is still not fully studied. The main difficulty is preparing high-quality films. In our study, we found that our newly designed benzimidazole-linked Cu (II)-phthalocyanine-based COFs (BICuPc-COFs) film can hardly formed with a regular aerobic oxidation method. Therefore, we developed a transfer dehydrogenation method with N-benzylideneaniline (BA) as a mild reagent. With this in hand, we successfully prepared a family of high crystalline BICuPc-COFs powders and films. Furthermore, both of these new BICuPc-COFs films showed high electrical conductivity (0.022-0.218 S/m), higher than most of the reported COFs materials. Due to the broad absorption and high conductivity of BICuPc-COFs, synaptic devices with small source-drain voltage (V DS =1 V) were fabricated with response light from visible to near-infrared. Based on these findings, we expect this study will provide a new perspective for the application of conducting heterocycle-linked COFs in synaptic devices., (© 2024 Wiley‐VCH GmbH.)
