Three‐Step Synthesis Toward Fluorene‐Based Non‐Fused‐Ring Acceptors for Organic Solar Cells
Chemistry – A European Journal, Volume 32, Issue 24, 23 June 2026.Applying a simple three step synthesis strategy leads to two fluorene‐based non‐fused‐ring electron acceptors, FHM‐Cl and FHM‐F for organic solar cells. The chlorinated variant delivers markedly higher efficiency due to broader light harvesting and favorable molecular packing, resulting in improved charge transport and reduced recombination losses ...

Chemistry – A European Journal, Volume 32, Issue 24, 23 June 2026.New redox‐active oligothioguanidines are developed and used in dehydrogenative P–P coupling reactions and hydroquinone oxidations. Tetrathioguanidino‐ and tetraguanidinobenzenes oxidize high‐potential halogenated hydroquinones faster than relatively low‐potential hydroquinone.
