ABSTRACT Two intrinsically flexible conjugated polymers, PBT‐90 and PFBT‐90 , were designed and synthesized via aldol polycondensation. Both polymers incorporate a novel double‐flexible‐node unit, 5,5'‐bis(1,1,2,2‐tetrafluoro‐2‐(thiophen‐2‐yl)ethyl)‐2,2'‐bithiophene, which can reduce brittleness and enhance recoverability in both bulk polymers and processed films. Both polymers displayed …

ABSTRACT Effective regulation of perovskite crystallization is crucial for achieving high‐performance perovskite solar cells (PSCs). However, perovskite films typically exhibit low crystallinity and are plagued by abundant bulk and grain boundary defects. Simultaneously controlling crystallization kinetics, defect passivation, and energy level alignment …

Abstract We report the design and synthesis of a series of bisisoindigo‐based donor–acceptor (D–A) copolymers, P4F18, P4F10, P2F18, and P2F10. By reverse evolution of fluorine substitution and side‐chain structure, we effectively tuned the frontier molecular orbital energy levels, intermolecular interactions, molecular self‐assembly, …

ABSTRACT Self‐assembled monolayers (SAMs) have emerged as promising hole transport layers in inverted perovskite solar cells (PSCs), yet their practical application is hindered by molecular aggregation, imperfect surface coverage, and weak interfacial interactions with the perovskite layer. These issues induce considerable interfacial …

Herein, the design, synthesis, and characterization of two novel electron-deficient building blocks were reported, namely, difluoroethylene-bridged bisazathienoisoindigos ( MF n, n = 1 and 2), and their polymer derivatives P1 – P4 . Crystal analysis and theoretical computations indicated that these building …
