The development of fully-conjugated semiconducting block-copolymers is an important goal for organic electronics, but to date has been almost exclusively limited to materials containing poly(3-alkylthiophenes). Here we present the prototype of a class of f ...

Uncovering the precise effect of the conjugated polymer chain length on the semiconducting properties in thin-film devices is confounded by the step-growth polymerization techniques typically used. Here, we use preparatory size exclusion chromatography to ...
The Stille-coupling polymerization of a short conjugated polymer with an aliphatic linker was used to demonstrate a prototype in a new class of polymer semiconductors wherein the conjugation segment length and the length of the entire chain can be independ ...
The ultimate control over chain self-assembly is key to unravel and optimize the relationship between film microstructure and charge carrier mobility in solution processable conjugated polymer semiconductors. Here we employ preparatory size exclusion chrom ...
