Plant LHC-like proteins show robust folding and static non-photochemical quenching [PDF]

Nature Communications, 2021
Plant light harvesting complex (LHC)‐like proteins protect the photosynthetic machinery from excess light. Here the authors show that plant LHC‐like dimers are stabilized by associated pigments and can quench chlorophyll fluorescence via direct energy ...

Static quenching upon adduct formation: a treatment without shortcuts and approximations

Chemical Society Reviews, 2021
Treatment of luminescence quenching upon adduct formation is often overlooked, leading to macroscopic errors. Here we provide a complete guide to its treatment, for correct mechanism assessment and to obtain reliable association constants.

Photocatalyst assemblies with two halide ions

Journal of Photochemistry and Photobiology, 2022
A series of ruthenium polypyridyl photocatalysts bearing amide functional groups were designed that successfully promoted halide assembly in CH2Cl2 and CH3CN solution. In CH2Cl2, halide assembly was accompanied by a visible color change, and the spectral

Spectroscopic Insights of an Emissive Complex between 4′-N,N-Diethylaminoflavonol in Octa-Acid Deep-Cavity Cavitand and Rhodamine 6G

Molecules, 2023
Excited-state chemistry relies on the communication between molecules, making it a crucial aspect of the field. One important question that arises is whether intermolecular communication and its rate can be modified when a molecule is confined.

Green synthesis of graphene quantum dots from Opuntia sp. extract and their application in phytic acid detection

Sensing and Bio-Sensing Research, 2021
Phytic acid and phytate anions are among the principal reserves of phosphorus. A few methods have been used for their detection, but these methods require harsh conditions.
