Abstract The polycondensation of a dihydrazino-pyrimidine (5 and 6) with a pyrimidine- dicarbaldehyde (7 and 8b) provides an efficent access to helical polymeric strands based on the formation of hydrazone connections between the pyrimidine groups. The folding into a helical structure is enforced by the helicity codon defined by the (hydrazone [BOND] pyrimidine) sequence. The polymers obtained have been characterized by mass ...
