Cross-conjugated chromophores: synthesis of iso-polydiacetylenes with Donor/Acceptor substitution
The iterative construction of cross-conjugated donor (D), acceptor (A), and donor-acceptor (D-A) substituted iso-polydiacetylene (iso-PDA) oligomers has been achieved utilizing palladium-catalyzed cross-coupling techniques. Structure-property relationships for these compounds have been analyzed for cross-conjugated pi-electronic communication as a result of contributions from donor, acceptor, or donor-acceptor functionalization.
