“…However, the ionic linkages of the developed electroactive ionenes are only limited to N,Ndimethyl-substituted ammonium cations connected by two rotatable, single-stranded hydrocarbon chains, which are subject to degradation through Hofmann eliminations, and perturbing the charge distribution and morphology. [37][38][39] 1,4-diazabicyclo[2.2.2]octane (DABC) features a cagedshaped diazabicyclic molecular structure with two tertiary sp 3 -nitrogen atoms at the bridgehead positions. Such less flexible framework also incurs an elevated energy barrier for the inversion of nitrogen atoms.…”

“…Until now, various of conjugated comonomers (NDI, PDI, and fullerene derivatives) and counter anionic species (halogen anions, hydroxyl and acetate) have been exploited to fine‐tune their optoelectronic properties and interfacial modification capabilities. However, the ionic linkages of the developed electroactive ionenes are only limited to N , N ‐dimethyl‐substituted ammonium cations connected by two rotatable, single‐stranded hydrocarbon chains, which are subject to degradation through Hofmann eliminations, and perturbing the charge distribution and morphology [37–39] …”

Electroactive ionenes combining caged-shaped diazabicyclic cations and aromatic diimides were developed as interlayers in organic solar cells (OSCs). These ionenes reduce the work-function of air-stable metal electrodes (e.g., Ag, Cu and Au) by generating strong interfacial dipoles, and their optoelectronic and morphological characters can be modulated by aromatic diimides, leading to high conductivity and good compatibility with active layers. The optimal ionene exhibits superior charge-transport, desirable crystallinity, and weak visible-absorption, boosting the efficiency of benchmark PM6 : Y6-based OSCs up to 17.44 %. The corresponding normal devices show excellent stability at maximum power point test under one sun illumination for 1000 h. Replacing Y6 with L8-BO promotes the efficiency to 18.43 %, one of the highest in binary OSCs. Notably, high efficiencies > 16 % are maintained as the interlayer thickness increasing to 105 nm, the best result with interlayer-thickness over 100 nm.
