3,5-Bis(trimethylsilyl)triphenyleno[1,12-bcd]thiophene

Abstract

In the title compound, C24H26SSi2, the fused ring system plus the two Si atoms are coplanar, consistent with planar triphenyl­ene but contrary to bowl-shaped triphenyl­eno[1,12-bcd:4,5-b′c′d′:8,9-b′′c′′d′′]trithio­phene. The bond alternation pattern of the C—C bonds in the title compound is similar to that found in triphenyl­eno[1,12-bcd:4,5-b′c′d′:8,9-b′′c′′d′′]trithio­phene, although the lengths of the C—C bonds around the central and thio­phene rings of the title compound are slightly different from the corresponding bonds of triphenyl­eno[1,12-bcd:4,5-b′c′d′:8,9-b′′c′′d′′]trithio­phene.
