Bis- and tris(arylethynyl)pyrimidine oligomers: synthesis and light-emitting properties
In this contribution, we describe the synthesis of bis- and tris(arylethylnyl)pyrimidine oligomers using Sonogashira, Negishi and Suzuki cross-coupling reactions and starting from chloro or iodopyrimidines. When the arms of such banana-shaped and star-sha
