摘要

Organic crystalline materials having a lamellar π?π stacked structural motif with short interplanar distance are significant for many applications. By asymmetrically introducing perfluoroalkyl substituents onto and polarizable sulfur atoms into N-containing heteroaromatics, we successfully synthesized a novel type of aromatic material that preferentially forms lamellar π?π stacked crystalline materials with a interplanar π?π distance of 3.247 ?, more than 0.1 ? shorter than that of highly oriented pyrolytic graphite (HOPG) where interplanar distance ranges from 3.35 to 3.39 ?.
