摘要：

Two different approaches for the synthesis of structurally defined ladder-type polymers are described. Repetitive Diels-Alder reaction as well as polymer analogous cyclization of suitable open-chain precursors are used for generating novel band-type structures. Polymeric [2.2]-cyclophanes and ethene-bridged polyacene precursors are prepared via [4 + 2] cycloaddition reactions. Ladder-type poly(p-phenylene) and oligo(perinaphthylenes) as planar pi-systems are obtained by Friedel-Crafts- rsp. by alkali-metal induced electrocyclic ring-closure reactions.
