The synthesis and chiroptical properties of a series of meta ‐arylenes, equipped with chiral oligo(phenylene vinylene) (OPV) side chains, are presented. How the OPV side chain contributes to the optical properties of the polymer is investigated. Secondly, the influence of the distance of the chiral moieties, placed on the OPV side chain, to the polymer main chain is investigated, which shows that, in order to induce any chiral effects, these chiral moieties need to be placed in the ß‐position near the polymer main chain. Finally, it is shown that long (a)chiral, lateral alkoxy chains on the OPV side chain prevent the polymers from adopting a helical conformation and result in the formation of lateral (a)chiral stacks of different polymer chains.
