Abstract
Palladium-catalyzed Stille and Sonogashira coupling reactions were sequentially applied for constructing novel pyrimidine-containing linear molecules. The chemoselectivity of 5-bromo-2-iodopyrimidine (1) towards Pd-catalyzed coupling reaction serves as a tool for the successful control of the arrangement of dipolar pyrimidine moieties inside the conjugated backbone. The influence of the arrangement of dipolar pyrimidine in the linear backbone on their absorption and photoluminescence are not stupendous. Thermogravimetric analysis (TGA) indicate that all linear molecules in this study exhibit high thermal stability. © 2001 Elsevier Science Ltd. All rights reserved.
