## Abstract The synthesis of poly(2,5‐dialkoxy‐__p__‐phenylene)s (PPP) by palladium‐catalyzed polycondensation of 2,5‐dialkoxy‐4‐bromophenylboronic acids is described. Number‐average degrees of polymerization of ca. 30 have been reached at best. The characterization of the polymers by NMR, IR, UV‐V
## Abstract A high‐molecular‐weight poly(2,5‐dialkoxy‐__p__‐phenyleneethynylene) derivative has been prepared by the Heck reaction of 1,4‐bis(2‐ethylhexyloxy)‐2,5‐diiodobenzene and 1,4‐diethynyl‐2,5‐dioctyloxybenzene. The highly luminescent polymer exhibits excellent solubility and can readily be p
## Abstract Hyperbranched poly(__p__‐phenylene ethynylenes) (HB‐PPEs) were synthesized in an A~2~ + B~3~ one‐pot approach by the Pd/Cu‐catalyzed cross‐coupling reaction of 1,4‐diethynyl‐2,5‐bis‐(octyloxy)benzene and 1,2,4‐tribromobenzene. Reaction conditions were varied with the objective to obtain
