[GRAPHICS]
The iterative construction of cross-conjugated donor (D), acceptor (A), and
donor-acceptor (D-A) substituted iso-polydiacetylene (iso PDA) oligomers h
as been achieved utilizing palladium catalyzed cross-coupling techniques. S
tructure-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.
