Impact of Electron‐Withdrawing Passivating Molecules on Perovskite Solar Cells

open access: yesChemSusChem, Volume 18, Issue 24, December 13, 2025.
The work reviews the effect of electron‐withdrawing groups on the photoelectric performance and stability of perovskite solar cells (PSCs), mainly focusing on the mechanism by which the group improves the performance and film quality of PSCs. Interfacial instability—originating from defects, ion migration, and uncontrolled crystallization—remains a ...

Pseudo‐Natural Products Inspired by Aspidospermidine‐, Strychnos‐, and Koumine Monoterpene Indole Alkaloids Reveal Pyrimidine Biosynthesis Inhibitors

open access: yesHelvetica Chimica Acta, Volume 108, Issue 12, December 2025.
Chemical evolution of alkaloids inspired the synthesis of a monoterpene alkaloid‐inspired pseudo‐natural product compound collection and revealed a novel de novo pyrimidine biosynthesis inhibitor chemotype. ABSTRACT In pseudo‐natural product (PNP) design, natural product fragments are combined in arrangements not found in nature to afford novel ...
