A series of five dicyanovinyl (DCV)-substituted aromatic compounds (referred to collectively as Ar-DCV, where Ar= 1-phenyl, 1-napthyl, 9-anthracenyl, 9-phenanthrenyl, and 1-pyrenyl) were prepared and their ground-and excited-state properties were examined. Solvent- dependent NMR studies indicate that the ground state of the Ar-DCV compounds is polar. Strong intramolecular charge transfer (ICT) absorption bands were observed for each ...
