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 ...
