Dipolar Nanocars Based on a Porphyrin Backbone
Résumé
The design and synthesis of a new family of nanocars
is reported. To control their motion, we integrated a
dipole which can be tuned thanks to strategic donor and acceptor
substituents at the 5- and 15-positions of the porphyrin
backbone. The two other meso positions are substituted
with ethynyltriptycene moieties which are known to act as
wheels. Full characterization of nine nanocars is presented
as well as the electrochemistry of these push-pull molecules.
DFT calculations allowed us to evaluate the magnitude of
the dipoles and to understand the electrochemical behavior
and how it is affected by the electron donating and accepting
groups present. An X-ray crystal structure of one nanocar
has also been obtained.
