Prof. John Anthony's publication titled "The Effect of Regioisomerism on the Crystal Packing and Device Performance of Desymmetrized Anthradithiophenes" was selected as a Hot Article for 2015 in the Journal of Materials Chemistry C, and as such it has been included in the Hot Article 2015 web collection, which can be viewed here (see page 2).  This publication showcases a new class of anthradithiophene derivatives, which are typically synthesized as an inseparable mixture of regioisomers.  The Anthony group reported a synthesis of desymmetrized anthradithiophenes that enabled the chromatographic separation of the resultant isomers and - in collaboration with Prof. Lynn Loo's group at Princeton University - found that certain pairs of isomers yield a field-effect mobility that is four orders of magnitude higher than the isomers when tested alone, which is presumably a result of a different packing motif.
