Bioinspired Microenvironments: Rational Design of High‐Mobility Semicrystalline Conjugated Polymers with Tunable Charge Polarity: Beyond Benzobisthiadiazole‐Based Polymers (Adv. Funct. Mater. 2/2017)

High‐Performance n‐Channel Organic Transistors Using High‐Molecular‐Weight Electron‐Deficient Copolymers and Amine‐Tailed Self‐Assembled Monolayers

“…The large domain sizes reduced the boundaries in the direction parallel to the channel, which is expected to be highly effective for the enhancement of the charge transport properties. [21,26,37] Overall, the morphology study was consistent with the TFT performances and GIWAXS results (vide supra).…”

“…These copolymers were composed of NDI and benzothiadiazole (BT) derivatives based on the newly developed regioregular donor-acceptor 1 -donor-acceptor 2 (D-A 1 -D-A 2 ) polymer backbone design strategy (pBTTz, pPTT, and pSNT, Scheme 1). [26] It should be noted that the backbone of pSNT is similar to that of a previously reported polymer, pNDI-SN. [26] However, most importantly, these polymers have different alkyl side chains (Chart S1, Supporting Information).…”

“…[26] It should be noted that the backbone of pSNT is similar to that of a previously reported polymer, pNDI-SN. [26] However, most importantly, these polymers have different alkyl side chains (Chart S1, Supporting Information). As proposed by Mei and Bao, selecting the suitable side chains is as important as developing polymer backbones.…”

Disruption of short-range π–π stacking via a disordered spatial architecture for energy storage at 250 °C

“…Compared with MPD-PI, both TAPA/M-PI and TAPM/M-PI exhibit a shift of peak 1 toward lower q values (from 1.199 to 1.171 Å À1 ), indicating looser chain packing and enlarged interchain spacing. 46 Furthermore, peak 2 gradually shifts from 1.777 Å À1 for MPD-PI to 1.690 Å À1 for TAPM/M-PI, corresponding to d E 3.7 Å, confirming the weakening of shortrange p-p stacking. 47 Combined with the PL results, these findings suggest that the tri-directional architecture introduced by TAPM disrupts the ordered p-p stacking and charge-transfer complexes (CTCs), leading to a more disordered insulating microstructure that stabilizes the excited states and suppresses high-field conduction losses.…”

A Tricyclic Framework with Integrated B←N and Cyano Dual Functionalization for Superior n‐Type Organic Electronics

“…These S•••O non‐covalent interactions effectively reduce steric hindrance, resulting in a smaller dihedral angle between the thiophene and benzene rings. For PMBNF and PMBNCN, the LUMOs are distributed across the most part of the skeleton, a phenomenon commonly observed in acceptor‐acceptor polymers with homogeneous LUMO distributions [29b] . In contrast, for PDBNF and PDBNCN, the LUMOs are primarily situated within the tricyclic cores, characteristic of donor‐acceptor polymers with distinct HOMO/LUMO distributions.…”
