Title: Inside Cover: Thiophene‐Based, Radial π‐Conjugation: Synthesis, Structure, and Photophysical Properties of Cyclo‐1,4‐phenylene‐2′,5′‐thienylenes (Angew. Chem. Int. Ed. 1/2015)
Abstract: Sulfur-Containing Carbon Nanorings whose phenylene and thienylene units are alternately connected within the ring structure, such as in cyclo-1,4-phenylene-2′,5′-thienylene (CPT), show remarkable photophysical and crystallographic properties, as described by K. Itami et al. in their Communication on page 159 ff. The illustrated picture (provided by Haruko Hirukawa) represents a [4]CPT molecule, which forms a truncated cone shape and interesting tubular stacking in the solid state, similar to onion rings.
