Fluorene-Based Multicomponent Reactions [PDF]

, 2022
Fluorene and fluorenone are privileged structures with extensive utility in both materials science and drug discovery. Here, we describe syntheses of those moieties through isocyanide-based multicomponent reactions (IMCRs) and the incorporation of the ...

Three-Step Synthesis Toward Fluorene-Based Non-Fused-Ring Acceptors for Organic Solar Cells. [PDF]

Chemistry
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 ...
