Conjugated polymers constitute the active materials in many organic electronic devices including OLEDs, FETs and solar cells. Phenylene and thiophene based materials show great promise for use in devices since their band gap can be fine-tuned through chemical manipulation. This talk will discuss the synthesis of a few classes of phenylene based materials for potential use in blue LEDs. Through appropriate structural modification, the emission in phenylene based materials can be adjusted to blue emission around 450nm where the human eye is most sensitive. Thiophene based oligomers have shown great promise in FETs whereas its polymers have been extensively studied as donor materials in organic photovoltaics. The synthesis of a few classes of oligothiophenes with thiophene-based solubilizing groups will be discussed. Among n-type materials, copolymers of benzothiadiazole based materials have shown great promise so far in FETs and solar cells. The synthesis of a functionalized bis(benzothiadiazole) and its incorporation into well-defined oligomers and polymers will also be discussed.
