Molecular, Crystal, and Thin‐Film Structures of Octathio[8]circulene: Release of Antiaromatic Molecular Distortion and Lamellar Structure of Self‐Assembling Thin Films

Abstract

And the film prize goes to…︁ octathio[8]circulene (2; see graphic), which, in contrast to the significant tub-shaped distortion observed for tetrathiophene (1), has a very planar structure in which the structural distortion caused by the 8π antiaromaticity is released. Reflecting the planar molecular structure, 2 forms lamellar thin films. The molecular and crystal structures of 1 and 2 were accurately determined by X-ray single-crystal analysis.
