摘要：

A modified route to ladder-type poly(p-phenylene)s is presented to reduce the amount of chromophorically inactive alkyl side chains attached to the double-stranded macromolecules. The novel synthetic sequence involves first the Pd(0)-catalyzed coupling of 2,5-dihexyl-1,4-phenylenediboronic acid with 2,3-dibromoterephthalic dialdehyde. A polymer-analogous addition of metalloorganic species followed by subsequent ring closure with BF3 then leads to the planar, soluble ribbon-type poly(phenylene)s.
