Ultrafast Energy Transfer Induced Lasing From a Coplanar Donor‐Acceptor‐Donor Molecule in a Microspherical Cavity

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a novel donor‐bridge‐acceptor‐bridge‐donor (D‐B‐A‐B‐D) molecular system, which shows near‐unity intramolecular excitation energy transfer (IET) from two identical energy donors to a coplanar acceptor. It enables a four‐level energy system for efficient lasing at the acceptor emission band in a microspherical cavity with a low lasing

Dual Side Chain Functionalization of Small Molecule Acceptors Affords High‐Performance Organic Solar Cells With Refined Blend Morphology

open access: yesAdvanced Functional Materials, EarlyView.
A new small‐molecule acceptor (SMA‐Ph‐CF3) is developed using a dual side chain functionalization strategy that incorporates trifluoromethyl and phenyl groups. This approach enables precise tuning of blend morphology, leading to the fabrication of high‐performance organic solar cells with a power conversion efficiency of 18.5%.

Understanding the Chemical and Electronic Properties of Sub‐Monolayer TiO2 on High Surface Area Silica for Jet Fuel Synthesis Applications

open access: yesAdvanced Functional Materials, EarlyView.
Sub‐monolayer titania grafted onto mesoporous silica enables solvent‐free photocatalytic upgrading of furfural and cyclopentanone into jet fuel precursors. Advanced spectroscopic methods reveal tunable surface speciation, acidity, and bandgaps, enhancing catalytic efficiency.

Double Cross‐Linked Hydrogel for Intra‐articular Injection as Modality for Macrophages Metabolic Reprogramming and Therapy of Rheumatoid Arthritis

open access: yesAdvanced Functional Materials, EarlyView.
A hydrogel for intra‐articular injection for the treatment of rheumatoid arthritis (RA) is formulated and comprehensively studied. After administration, the hydrogel induces a metabolic reprogramming of immunometabolism of macrophages to trigger fatty acid oxidation subsequently inducing polarization of anti‐inflammatory M2 macrophages. This results in
