Efficient CO Bond Cleavage in the Oxidized β‐O‐4 Lignin Motif Using a Carbon‐Supported Cobalt Catalyst

ChemNanoMat, Volume 11, Issue 12, December 2025.
Cobalt‐based M–N–C catalysts are evaluated for the transfer hydrogenolysis of oxidized lignin model compounds using formic acid. The synergy between cobalt nanoparticles (CoNPs) and sub‐nanometric Co(II) species in a N‐doped carbon matrix enables efficient CO bond cleavage under mild conditions.

Multi‐channel charge transfer delayed fluorescence enabling high‐efficiency organic light‐emitting diodes

FlexMat, Volume 2, Issue 4, Page 533-581, December 2025.
The enhanced utilization of triplet excitons is a central theme in the evolution of organic luminescent materials. This review sums up recent research on multi‐channel charge transfer delayed fluorescence molecules, which exhibit a unique distribution of excited‐state energy levels, thereby enhancing the utilization rate of triplet excitons and ...
