Over 18% Efficiency from Halogen‐Free Solvent‐Processed Polymer Solar Cells Enabled by Asymmetric Small Molecule Acceptors with Fluoro‐Thienyl Extended Terminal

Advanced Functional Materials, EarlyView.
An asymmetric non‐fullerene acceptor BTP‐FT is developed by extending the end group of Y6‐BO with thiophene. The conformation of the molecule is determined by the noncovalent F···S interaction as demonstrated by 2D NMR and simulations. An efficiency of 18.39% is achieved in the resulting ternary solar cells processed from toluene.

Multifunctional Hydroxyapatite Coated with Gallium Liquid Metal‐Based Silver Nanoparticles for Infection Prevention and Bone Regeneration

Advanced Functional Materials, EarlyView.
A multifunctional hydroxyapatite (HAp) coating integrated with silver‐gallium liquid metal nanoparticles (HAp‐Ag‐GaNPs) exhibits dual antibacterial and osteogenic properties. It effectively inhibits Gram‐positive and Gram‐negative bacteria, including resistant strains, while enhancing bone regeneration.

Exploring Electronic States and Ultrafast Electron Dynamics in AlInP Window Layers: The Role of Surface Reconstruction

Advanced Functional Materials, EarlyView.
This study examines the surface characteristics of AlInP (001), crucial for advanced solar cells and photoelectrochemical devices. Using theoretical modeling and experiments, it identifies how phosphorus‐rich and indium‐rich surfaces create mid‐gap states that pin the Fermi level and influence ultrafast electron dynamics.

Rigid Fluorescent Indacenetetraone‐Based Semiconducting Polymers via Knoevenagel Condensation

Advanced Functional Materials, EarlyView.
New donor–acceptor polymers prepared by Knoevenagel condensation of indacenedithiophene‐ and indacenedifuran‐based aldehydes reveal an exceptionally rigid backbone, which is manifested in the remarkably narrow absorption and emission bands in red to near‐infrared region.
