Morphological and electrical control over conjugated polymers has a great potential for the fabrication of high-performance organic thin-film transistors (OTFTs). Herein, we employed multifunctional polymeric additive, namely, PBTTT-b-HTPB, to optimize molecular packing order an isoindigo-based model polymer (IIDSiC8) simultaneously regulate minority carriers boosted transport properties in OTFTs via facile solution processing. By detailed comparative study, demonstrated that PBTTT-b-HTPB remarkably improved crystallinity IIDSiC8 by forming elongated fibers with higher thin film, which originated from larger size ordered aggregates due presence insulating block. On other hand, p-type block PBTTT worked as hole trapping center, resulting significantly increased electron density, reduced off-current, optimal n-type performance.

Fine-tuning the charge polarity and enhancing electron transport in conjugated polymers are critical for developing high-performance organic field-effect transistors (OFETs). Quinoidal polymers, characterized by planar backbones deep-lying lowest unoccupied molecular orbital (LUMO) energy levels, offer distinct advantages over their aromatic counterparts but face challenges achieving reliable mobilities exceeding 1 cm2 V–1 s–1. Herein, we synthesized a set of novel quinoid–donor–acceptor (Q-D-A) with various acceptor units. Increasing strength narrowed band gap, lowered LUMO shifted from unipolar p-type to ambipolar ultimately dominant n-type behavior. The electron-to-hole mobility ratio increased 0 40 behavior observed Q-D-A polymer first time. Consequently, strongest acceptor-based exhibited backbone, small effective mass, high crystallinity, low disorder, resulting 1.20 s–1 decent operational stability. This is record-high value quinoidal transport. Our findings viable strategy tuning improving providing insights into structure–property relationships essential advancing electronics.

Cross conjugation, though prevalent in many organic compounds, is typically considered less effective for electron delocalization compared to linear conjugation. Consequently, it rarely used as the backbone structure semiconducting conjugated polymers. In this study, we designed and synthesized a novel building block, TIDP, which features central cyclic dipeptide with cross conjugation characteristics. Strong intramolecular hydrogen bonding interactions confer TIDP highly rigid coplanar conformation. Importantly, theoretical calculations reveal that π electrons are well delocalized across entire structure, despite its low aromaticity. Conjugated polymers incorporating exhibit high charge carrier mobilities, demonstrating of innovative block. Our findings show rational design, can achieve delocalization, providing valuable approach developing high-performance electronic materials.
