Co-crystallization of Thiophene-based Semiconductors with Carboxylic Acids and Effects on Crystal Packing

Organic semiconductors are of high interest due to a promise of low cost, flexible electronics. Solid state packing of organic semiconductors impacts electrical properties. We have shown that addition of a semiconductor co-crystal former (SCCF) impacts solid state packing by increasing pi-pi interactions between adjacent semiconductor molecules.1 Here, we report initial findings on how SCCFs with different carboxylic acids affect the solid-state packing of thiophene based semiconductors. 1Sokolov, A.
