Ultrafast Dynamics of Organic Exciton–Polaritons

Nanophotonics, Volume 15, Issue 6, 27 March 2026.
This work reveals the conditions required to capture the coherent dynamics of organic exciton–polaritons. The ultrafast relaxation of these collective hybrid states is uniquely observed only when they sit beyond the tail of the molecular absorption. In this condition, they do not enter into equilibrium with intracavity dark states, raising questions ...

Intramolecular Down‐ and Up‐Conversion in Dimeric Tetracene Complexes Centered via Platinum(II) and Palladium(II)

Advanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
Metal‐tetracene dimeric complexes are synthesized through the pyridyl coordination to either Pt(II) or Pd(II). Photophysical properties are systematically compared as a function of the metal using steady‐state and time‐resolved spectroscopy. The Pt(II) dimer exhibits efficient intramolecular singlet fission and subsequent intramolecular up‐conversion ...

An Overview of Polyphenols and Color Chemistry in Cocoa

AgriFood: Journal of Agricultural Products for Food, Volume 2, Issue 1, Page 80-95, March 2026.
Cocoa polyphenols have been traditionally known for their beneficial properties in human health. However, less is known about their other impacts on cocoa processing. This review highlights current discoveries in the role of polyphenols in the formation of color in cocoa.

Tailoring Biomass‐Derived Organosolv Lignin Derivatives for High‐Capacity Adsorption of Rhodamine B

ChemSusChem, Volume 19, Issue 4, 25 February 2026.
Organosolv lignin derivatives modified with phenolic compounds were synthesized via a one‐step lignin‐first approach and evaluated as renewable adsorbents for removing Rhodamine B dye from water. Among them, resorcinol‐modified lignin showed the highest adsorption capacity (101 mg g−1), driven by high surface area, pore volume, and accessible hydroxyl ...
