Enantiopure 2-(2-ethylhexyl)dinaphtho[2,3-b:2',3'-f]thieno[3,2-b]thiophenes: synthesis, single-crystal structure and a surprising lack of influence of stereoisomerism on thin-film structure and electronic properties.

Abstract: Starting from a chiral resolution of 2-ethylhexanoic acid followed by conversions of functional groups without interfering with the enantiopurity, we have successfully introduced an enantiopure 2-ethylhexyl group on to dinaphtho[2,3-b:2',3'-f]thieno[3,2-b]thiophene (DNTT) via a Negishi-coupling reaction… read more here.

Abstract: Stereoisomerism is one of the most fundamental and indispensable notions in chemistry. We have recently found that a novel form of stereoisomerism emerges in cycloarylenes, cyclic arrays of aromatic panels. Structural rigidity that is a… read more here.
