Abstract

Abstract To investigate the potential of di-and tri-azaheterocycles as building blocks for π- conjugated materials with high electron affinity, linear oligomers incorporating pyrazine and a C 3-symmetric discotic molecule based on triazine were synthesized. The tridodecyloxyphenyl end-capped ethynylene pyrazinylene oligomers showed remarkable solvatochroism in absorption and emission in solution. The oligomers containing one and ...
