Abstract
The article reports the surface-assisted synthesis of a non-planar cyclophenylene derivative containing four meta- and two para-connected phenylene moieties on Au(111), via hierarchical Ullmann coupling of a 1,10 dibrominated angular [3]phenylene and subsequent C–C bond cleavage at the four-membered rings. Scanning tunneling microscopy and spectroscopy (STM/STS) were used for the characterization of its chemical structure and electronic properties. Density functional theory (DFT) calculations support the experimental observations
