Helical polymers appended with paired structurally different enantiomers, which have opposing helical sense preferences, yield a new kind of relationship between optical activity and temperature, and also reveal unusual details of the nature of chiral int

The chiral cis- and trans-azo compounds 8a - d and 9a - d with para- or ortho-standing chiral side chains as well as the trans-azoxy derivatives 17a - d and 18a - d are synthesized.The influence of the molecular structure and the distance of the chiral centre from the aromatic nucleus on screw sense and pitch of induced cholesteric phases is investigated.The cis-azo compounds 9c and d show atropisomerism.
