Abstract Herein, bis‐sulfonimide (BSI), characterized by multiple d ‐ p π bonds rather than typical bonds, is unprecedently utilized as a general and extendable building block to develop series of multifunctional cathode interlayer materials (CIMs) for organic solar cells (OSCs). An illustrative CIM, BSIz‐TT‐PDI, demonstrates favorable alcohol processability, superior work function tunability, appropriate energy levels, strong self‐doping effect, decent crystallinity. These attributes contribute its high conductivity exceeding 5×10 −3 S/cm, well precise optimization the interfacial connection between active layer metal cathode. Therefore, BSIz‐TT‐PDI‐based OSCs delivers an outstanding efficiency 18.08 % using PM6:Y6 while retaining 84 initial performance after tracking at maximum power point under continuous illumination 1100 hours. Additionally, devices maintain over 94 optimal across film thickness range BSIz‐TT‐PDI from 5 90 nm. Moreover, exhibits compatibility with various layers, enabling record 19.80 PM6:BTP‐eC9:L8‐BO layer. This not only introduces new library water/alcohol‐soluble n‐type semiconductors containing BSI, also pioneers creation thickness‐insensitive CIMs stable efficient integrating electron‐withdrawing components bonds.

Abstract Recently, the palladium‐catalyzed direct arylation polymerization (DArP) has emerged as a viable alternative to conventional synthetic means of making π‐conjugated polymers based on catalytic cross‐coupling reactions. The DArP, which proceeds through C−H bond activation, distinct advantage over in terms fewer reaction steps and higher functional group tolerance. We have developed novel catalysts for DArP by using P(2‐MeOC 6 H 4 ) 3 ( L1 P(2‐Me 2 NC L2 ligands. Although common require use strongly coordinating solvents such DMA DMF, our exhibit high activity THF toluene, are good polymers. Thus, we could realize precise synthesis highly head‐to‐tail regioregular poly(3‐hexylthiophene) (HT‐P3HT) donor–acceptor type alternating copolymers (DA polymers) with well‐controlled structures DArP.

Organic photovoltaics have attracted much attention in the past few years, mainly due to their ability be fully printed at low cost and large scale. However, organic semiconductors utilized as active layer are typically synthesized using Migita–Stille or Suzuki–Miyaura cross-coupling, which is not efficient may bring toxicity concerns. In search for atom-economical synthesis, direct (hetero)arylation polymerization (DHAP) enables activation of aromatic C–H bonds, both reducing synthetic steps monomers toxic reaction byproducts. this issue, we will discuss recent contributions on synthesis toward mass production photovoltaic materials. The impact DHAP material efficiency addressed compared conventional coupling methods. ongoing improvements discussed, becomes more sustainable higher scale materials observed having quality.
