Abstract

We report the synthesis, one-and two-photon absorption spectroscopy, fluorescence, and electrochemical properties of a series of quadrupolar molecules that feature proquinoidal π- aromatic acceptors. These quadrupolar molecules possess either donor− acceptor− donor (DAD) or acceptor− donor− acceptor (ADA) electronic motifs, and feature 4-N, N- dihexylaminophenyl, 4-dodecyloxyphenyl, 4-(N, N-dihexylamino) benzo [c][1, 2, 5] ...
