THE SOLID STATE STRUCTURE OF 9,11,20,22-TETRAPHENYLTETRABENZOPENTACENE-10,21-DIONE: A LONGITUDINALLY TWISTED MOLECULAR RIBBON

Article abstract of DOI:10.1016/S0040-4039(00)95710-1

An X-ray crystallographic analysis of the title compound (1) shows that this fused-ring polycyclic molecule is greatly distorted from planarity.The structure is centrosymmetric, and the mean plane of the center ring is twisted by approximately 48 deg rela
