The incorporation of alternating 1,3- and 1,4-phenylene subunits into a planar, rigid ladder-type polymer leads to polyphenylene macromolecules of high structural regularity. The polymer is formed in a two-step process involving the preparation of a suitably substituted polyphenylene backbone, followed by ring closure via polymer-analogous Friedel-Crafts cyclization. The ladder-type polyphenylene is an appropriate precursor for generating polymers with 1,4-benzoquinone-bismethide substructures
