Zhao, Zujin published the artcileNovel, yellow-emitting anthracene/fluorene oligomers: synthesis and characterization, Quality Control of 18512-55-5, the publication is Tetrahedron (2007), 63(33), 7809-7815, database is CAplus.
Five highly soluble and strongly yellow fluorescent oligoalkyne dyes with well-controlled, alternating anthracene and fluorene units were successfully synthesized by a Pd/Cu-catalyzed Sonogashira coupling reaction and characterized. Their thermal stabilities, electrochem. behaviors, and photophys. properties were investigated. These oligomers might be used as models to study structure-property relationship for their corresponding polymers and applied in optoelectronics devices as materials themselves.
