Summary: A cyclo[2]carbazole[2]pyrrole (2), composed of two carbazoles and two pyrroles, was synthesized by directly linking the carbazole 1- and 8-carbon atoms to the pyrrole alpha-carbon atoms. The resulting macrocycle 2 has an extensively conjugated 16-membered macrocyclic ring and a preorganized anion binding site consisting of two pyrrole subunits. H-1 NMR spectroscopic analysis revealed that only the diagonally opposed pyrrole NH protons are involved in anion binding, and cyclo[2]carbazole[2]pyrrole 2 binds anions with higher affinity than calix[4]pyrrole (1). Computational studies suggest that the higher anion affinity of receptor 2 is due to its larger binding energy and lower host strain energy associated with anion complexation. In the presence of excess fluoride or bicarbonate anions, compound 2 loses two pyrrolic NH protons and forms a stable dianionic macrocycle [2-2H](2-) with quenched fluorescence.

Summary: This study presents high-performance perovskite solar cells (PSCs) based on a composite of perovskite and a low optical gap conjugated polymer. The composite film exhibits enhanced charge carrier mobility, larger crystal sizes, and suppressed non-radiation charge carrier recombination. Additionally, a photo-induced charge transfer occurs within the composite film, leading to improved power conversion efficiency (PCE) of the PSCs. The un-encapsulated PSCs also demonstrate enhanced stability and reduced photocurrent hysteresis compared to those based on pristine perovskite films.

Summary: Recyclable conjugated polymers play a crucial role in eco-friendly electronics due to their solution processability and flexibility. A recyclable conjugated polymer, PY-TIP, has been developed, in which a key monomer is extracted and reused for synthesizing new conjugated polymers. A one-shot preparation method using the recycled monomer has been demonstrated for the first time, resulting in a bulk-heterojunction (BHJ) film with optimal nanoscale morphology for efficient charge generation and transport. Solar cells prepared with the BHJ film exhibit a higher efficiency of 13.08% and improved thermal and mechanical stability compared to those based on small molecular acceptors. These results highlight the potential of solid-state polymer synthesis from recycled monomers and the importance of improving both stability and photovoltaic performance in BHJ films. PY-TIP serves as an exemplary model for reproducing monomers and synthesizing conjugated polymers with novel properties. This work provides valuable insights for developing recyclable conjugated polymers with dynamic covalent bonds.

Summary: The development of commercially viable organic solar cells (OSCs) requires reducing the efficiency-stability-cost gap. This can be achieved by minimizing synthetic steps while maintaining molecular planarity and efficiencies achieved by fused ring acceptors (FRAs). Developing non-fused ring acceptors (NFRAs) with suitable functionalization for conformational planarity and molecular packing can be cost-effective. Although NFRAs currently have a power conversion efficiency (PCE) of around 16%, lower than FRAs' 19%, understanding their effective structural design is crucial for efficient OSC development. This article focuses on the molecular design concept for NFRAs in recent years and analyzes the approach to material design and efficiency improvement, a significant step toward technological application.

Summary: This work focuses on the application of hydrated vanadium pentoxide (HVO) as a hole transport layer (HTL) in organic solar cells (OSCs). The simple synthesis process of HVO as the anode HTL in non-fullerene-acceptor-based binary and ternary OSCs enables a higher power conversion efficiency (PCE). The comparison experiments show that the OSCs based on ITO/HVO anode exhibit a higher PCE than those based on ITO/PEDOT:PSS anode.
