D. Cole, Madhu Sheri, Chelsea Bielicki, Todd EmrickA series
of perylene diimide (PDI)-containing ionene and zwitterionic
polymers were prepared by the Menschuktin reaction and by nucleophilic
ring-opening of a novel bis-sultone monomer. PDI derivatives containing
tertiary amine moieties at the imide position, and bromides or phenyl
groups within the aromatic core, provided sites for polymerization
and imparted solubility during the polymerization, respectively. The
solution photophysical behavior of the polymers was studied by UV–vis
and photoluminescence spectroscopy as a function of PDI incorporation
and cationic/zwitterionic functionality, resulting in the observation
of tunable solution spectral features induced by core functionality
and/or interzwitterion interactions. This new PDI-based polymer platform
affords opportunities to modulate conjugation and charge density within
the polymers and examine the effects of cationic vs zwitterionic groups
on the resultant optoelectronic properties.
