Poly(isocyanidcs), ( R N = C < ) n, can be prepared from isocyanidcs, R N += C " , by the catalytic action of nickel(II) compounds. The main chain of these polymers is a rigid helix. This helical conformation results from a restricted rotation around the single bonds that connect the main-chain carbon atoms. Polymerization of achiral isocyanides generally gives a racemic mixture of leftand righ...

Relationships between chiroptical properties (Optical Rotatory Dispersion, ORD, and Circular Dichroism, CD) and Conformation of structur— ally simple isotactic polymers and copolymers derived from optically active monomers are reviewed. Both experimental and calculated values fit with chain cotiformations consisting prëdomirantly of one screw sense helical sections due to dissyinmetric cooperat...

Recent work on non-conjugated pendant electroactive polymers (NCPEPs) has demonstrated significant impacts of structural parameters such as backbone stereoregularity and the spacer connecting to properties, most notably charge carrier mobilities. Tuning group however not been reported for stereoregular NCPEPs. Here we present a family novel isotactic poly((carbazolyl-alkyl-triazolyl)methyl meth...
