Carbon Dot Self‐Assembly: Bottom‐Up Fabrication, Morphological Evolution, Luminescence Regulation, and Advanced Applications

Aggregate, Volume 7, Issue 5, May 2026.
The self‐assembly of carbon dots, which enables precise control over their macroscopic architectures and collective properties, profoundly enhances their functionality. This review systematically summarizes the field through four key aspects—morphology control, luminescence modulation, assembly mechanisms, and advanced applications—and thereby offers a

Oxygen‐Acceptor‐Driven High Photochromic Contrast Solid‐State Excited‐State Intramolecular Proton Transfer Photoswitches

Angewandte Chemie, Volume 138, Issue 18, 27 April 2026.
The excited‐state intramolecular proton transfer (ESIPT) photoswitch tpmSA, which features an oxygen−acceptor, exhibits higher photochromic contrast (ΔE*Lab>74) than its nitrogen‐acceptor Schiff base analogues (ΔE*Lab<30). Theoretical calculations indicate that tpmSA effectively suppresses GSIPT, thereby enhancing the contrast.

Sample Preparation and Separation of Lignans by Liquid Chromatography

Journal of Separation Science, Volume 49, Issue 5, May 2026.
ABSTRACT Lignans are important phytochemicals found mostly in the resins of coniferous trees, but are also introduced into human diets through foods such as sesame seeds and extra‐virgin olive oil. They are pharmacologically interesting mainly because of their antioxidant activities, and they have also been shown to have cytotoxic and antimicrobial ...

Engineering Robust Supramolecular Nanoassemblies from Amino‐Acid Functionalized Stiff‐Stilbene Amphiphiles

Small Science, Volume 6, Issue 5, May 2026.
This study reports a newly designed stiff‐stilbene amphiphile functionalized with alanine amino acid groups (SAAla), incorporating advanced π–π interactions between stiff‐stilbene cores and amide hydrogen bonding to dictate the intermolecular distance and enable the construction of supramolecular nanostructures with pH and thermal stability, achieved ...
