A series of linear π conjugated arylene oligomers based on 1,5-naphthalene subunit: synthesis, characterization, and properties

摘要

A series of novel alkoxy-substituted arylene-ethynylene oligomers based on 1,5-naphthalene subunit have been successfully synthesized by palladium-catalyzed cross-coupling reaction. The solubility, thermal, optical, and electrochemical properties have been investigated in detail. The title compounds are soluble in common organic solvents and emit a blue color both in solution and in the solid state, indicating that these oligomers might serve as potential materials in optoelectronic devices.
