Abstract

A face-to-face π-stacked one-dimensional (1D) assembly of π-conjugated discotic molecules is a promising superstructure for organic semiconductor materials. In their article, I. Hisaki, M. Miyata et al. on page 4178 ff. describe the construction and the optical and electrical properties of a π-stacked 1D assembly composed of a dehydrobenzo[12]annulene derivative in the crystalline state. Compared with the herringbone-like assembly of the parent annulene, the 1D assembly revealed significantly-anisotropic charge mobility (Σμ=1.5×10−1 cm2 V−1 s−1) along the columnar axis.
