Zone refining of anthracene [PDF]

, 1957
The process of zone refining involves the passage of a molten zone along a rod of solid. As the zone progresses, composition of the material freezing out generally differs from that melting, so solutes are redistributed. Enrichment of the major component

9,10-Bis(5H-dibenzo[b,f]azepino)anthracene

Molbank
The title compound with a donor–π–donor (D–π–D) type triad structure was synthesized by Buchwald–Hartwig amination using 9,10-dibromoanthracene and 5H-dibenzo[b,f]azepine, and characterized by 1H, 13C{1H} NMR, HRMS, and X-ray diffraction analysis.

Crystal structure and theoretical studies of two π-conjugated fused-ring chalcones: (E)-1-(anthracen-9-yl)-3-(9-ethyl-9H-carbazol-3-yl)prop-2-en-1-one and (E)-1-(anthracen-9-yl)-3-[4-(9H-carbazol-9-yl)phenyl]prop-2-en-1-one

Acta Crystallographica Section E: Crystallographic Communications, 2018
The title chalcones, C31H23NO and C35H23NO, were synthesized via Claisen–Schmidt condensation reactions. Both structures were solved and refined using single-crystal X-ray diffraction data and optimized at the ground state using the density functional ...

Zero‐Valent Nickel Stabilized in Surface‐Supported Metal–Organic Chains

Angewandte Chemie International Edition, EarlyView.
9,10‐Dicyanoanthracene coordinates Ni atoms on Ag(100) to form metal–organic chains that stabilize zero‐valent Ni(0) (d10) centers with quasi‐one‐dimensional metal–ligand electronic coupling. ABSTRACT The stabilization of zero‐valent nickel Ni(0) centers in extended coordination networks remains a major challenge due to their pronounced reactivity and ...
