Abstract

A method of regioselectively preparing a pyridine-containing compound is provided. In particular embodiments, the method includes reacting halogen-functionalized pyridal[2,1,3]thiadiazole with organotin-functionalized cyclopenta[2,1-b:3,4-b']dithiophene or organotin-functionalized indaceno[2,1-b:3,4-b′]dithiophene. Also provided is a method of preparing a polymer. The method includes regioselectively preparing a monomer that includes a pyridal[2,1,3]thiadiazole unit; and reacting the monomer to produce a polymer that includes a regioregular conjugated backbone section, wherein the section includes a repeat unit containing the pyridal[2,1,3]thiadiazole unit. A polymer that includes a regioregular conjugated backbone section, and electronic devices that include the polymer, are also provided.
