Synthesis and molecular properties of donor-pi-spacer-acceptor ynamides with up to four conjugated alkyne units.
A set of push-pull ynamides with up to four conjugated triple bonds has been synthesized and the molecular properties of these new carbon rods have been characterised showing effective intramolecular charge transfers and high values for the change of the electrical dipole moment after transition from the ground to the Franck-Condon excited state.
