| 英文摘要 | Side chains of conjugated polymers (CPs) have played a vital role in the regulation of solution processibility and semiconducting performance. Herein, carbosilane side chains, which manifest the advantages of low-cost and facile synthesis as compared to the common alkyl ones, were employed to regulate the aggregation behaviors and charge transport properties of isoindigo-based polymers. Three polymers, IIDSiC12, IIDSiC8, and IIDC12, with carbosilane side chains of varying bulkiness and alkyls as the control were synthesized via direct arylation polymerization. Anisotropic one-dimensional pre-aggregates of different aspect ratios were developed in solution, as disclosed by solution small-angle neutron scattering, which further determined the order of the microstructure in bar-coated films for organic thin-film transistors (OTFTs). It is noteworthy that the relatively large radius (20.5 Å) and moderate aspect ratio (∼20) of IIDSiC12 solution aggregates ensured a solid-state microstructure of the highest order, as evidenced by well-aligned fiber-like morphology and the largest range of packing order. As a result, OTFTs based on IIDSiC12 achieved the maximum saturation electron mobility up to 4.10 cm2 V-1 s-1 with a reliability factor of 81%, which is among the highest mobilities of n-type CPs. The results reported here may encourage the easier synthesis of high mobility CPs using the carbosilane side chain engineering. © 2022 American Chemical Society. |
