Abstract
The lattice of 5,7,12,14-tetrahydro-5,14: 7,12-bis([1,2] benzeno) pentacene-6,13-dione, C34H20O2, at 173 K has triclinic (P (1) over bar) symmetry and crystallizes with four independent half-molecules in the asymmetric unit. Each molecule is generated from a C17H10O substructure through an inversion center at the centroid of the central quinone ring, generating a wide H-shaped molecule, with a dihedral angle between the mean planes of the terminal benzene rings in each of the two symmetry-related pairs over the four molecules of 68.6 (1) (A), 65.5 (4) (B), 62.3 (9) (C), and 65.8 (8)degrees (D), an average of 65.6 (1)degrees. This compound has applications in gas-separation membranes constructed from polymers of intrinsic microporosity (PIM). The title compound is a product of a double Diels-Alder reaction between anthracene and p-benzoquinone followed by dehydrogenation. It has also been characterized by cyclic voltammetry and rotating disc electrode polarography, FT-IR, high resolution mass spectrometry, elemental analysis, and H-1 NMR.
