Extension of the π-conjugated core of methylchalcogenolated polycyclic aromatic hydrocarbons: synthesis and characterization of 1,4,7,10-tetrakis(methylthio)- and tetramethoxy-coronene.

ABSTRACT: Controlling the crystal structures of polycyclic aromatic hydrocarbons (PAHs) by regioselective methyl chalcogenolation is an effective strategy for realizing superior molecular semiconductors showing ultrahigh mobility, as exemplified by methylthiolated pyrene and peropyrene. Following the strategy, we designed and synthesized 1,4,7,10-tetrakis(methylthio)coronene (MT-coronene) and 1,4,7,10-tetramethoxycoronene (MO-coronene) as potential candidates for high-performance molecular semiconductors. Since the coronene core is highly symmetric, the regioselective functionalization at the 1, 4, 7, and 10-positions seemed to be challenging, and thus, we tested two strategies for constructing such regio-selectively functionalized coronene derivatives: one was the direct functionalization of the pa
