Photochemistry of Resveratrol: Beyond the Reactivity of Metal‐Free Porphyrins Immobilized on Lignin

open access: yesChemPhotoChem, EarlyView.
Resveratrol photochemistry with singlet oxygen is examined at 450 nm using blue‐LED irradiation and various homogeneous and heterogeneous photosensitizers. Products of CC bond cleavage, electrocyclic ring closure, and [4 + 2] cycloaddition are identified.

Enhanced Performance of NiO‐Based Dye‐Sensitized Solar Cells Using a Covalent Porphyrin‐C60 Dyad

open access: yesChemPhotoChem, EarlyView.
The preparation and complete characterization of a covalent ZnPor‐C60 donor–acceptor dyad and its study in p‐type dye‐sensitized solar cells are described. This novel dyad contains an oligo(p‐phenylenevinylene) bridge, which elongates the distance between the electron donating and accepting units, leading in achieving significantly enhanced ...

Selective Modification of the Product Profile of Biocatalytic Hydrolyzed PET via Product‐Specific Medium Engineering

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
The product profile of enzymatically hydrolyzed PET can be modified by medium engineering and thereby adapted to a desired product. TPA, MHET or BHET can be forced as the predominant product using a basic pH (blue), 25 % ethylene glycol (EG) and IsPETasewt (green) or ≥25 % EG and LCCICCG (pink), respectively.
