Strukturaufklärung eines doppelsträngigen Polymers mittels Modellstudien

Abstract
Structure Elucidation of a Double‐Stranded Polymer by Using Model StudiesSyntheses and complete structural characterization (including constitution, configuration, conformation) of the double‐stranded compounds Ua‐5b, Ss‐5b, U‐7b, S‐7b, UUa‐8, SUs‐8, UUUaa‐9, USUas‐9, SUUsa‐9, and SSuss‐9 are described. These compounds contain up to three repeating units of the ladder polymer 3 and are therefore used as model compounds to elucidate interesting structural aspects of this polymer. A model for the spherical shape of 3 is presented. The molecular structures in the crystals of S‐7b, SUs‐8, Ua‐5b have been determined.
