Abstract
Abstract Kumada-Tamao coupling polymerization of 6-bromo-3-chloromagnesio-2-(3-(2- methoxyethoxy) propyl) pyridine 1 with a Ni catalyst and Suzuki-Miyaura coupling polymerization of boronic ester monomer 2, which has the same substituted pyridine structure, with t Bu 3 PPd (o-tolyl) Br were investigated for the synthesis of a well-defined n- type π-conjugated polymer. We first carried out a model reaction of 2, 5-dibromopyridine ...
