Cationic Diazapentacenium Polymers Made in a Sequence of CN Cross Coupling Polymerization and Acid‐Mediated Postpolymerization Cyclization

Polycationic stepladder polymers containing 5,12‐diazapentacenium bistriflate repeat units are made in a two‐step sequence of a carbon‐nitrogen cross coupling polymerization and subsequent postpolymerization cyclization. The deeply colored products show a rather weak conjugative interaction between...

Description
Summary:	Polycationic stepladder polymers containing 5,12‐diazapentacenium bistriflate repeat units are made in a two‐step sequence of a carbon‐nitrogen cross coupling polymerization and subsequent postpolymerization cyclization. The deeply colored products show a rather weak conjugative interaction between the dicationic diazapentacenium repeat units along the polymer chains. Polycationic stepladder polymers with 5,12‐diazapentacenium bistriflate repeat units are made in a sequence of cross‐coupling polymerization and postpolymerization cyclization. The polyelectrolytes show an only moderate electronic coupling between the polycyclic repeat units.
