title: New chiral pi-conjugated polymers based on a (1R,2R)-diiminocyclohexane chiral unit with weak interchain pi stacking.
abstract: New chiral pi-conjugated polymers consisting of alternating conjugated segments and (1R,2R)-diiminocyclohexane units with C2 symmetry were prepared by a palladium-catalyzed coupling reaction, they exhibited very high specific optical rotations ([alpha] up to -3000 degrees) and strong Cotton effects ([theta] 10(6) deg cm2 mol-1).
