SYNTHESIS AND PROPERTIES OF POLY(AROMATIC DIACETYLENE)S CONTAINING FLUORENE

Received Date: 20 March 2007
Revised Date: 25 April 2007

Novel fluorene-based poly(aromatic diacetylene)s have been synthesized by CuCl-catalyzed oxidative coupling of aromatic diynes. New aromatic diynes 2,7-diethynyl-9,9-bis(triphenylamine)fluorene (M1) is synthesized by multistep reactions. The structures and properties of the polymers are characterized and evaluated by IR, NMR, TGA, UV, photoluminescence (PL), and cyclic voltammetry analyses. These polymers possess good thermal stability. All the polymers are completely soluble in common solvents such as toluene, THF, chloroform, and dichloromethane. The polymers exhibit strong blue photoluminescence in solution and green photoluminescence in the solid state. The polymer containing triphenylamine-substituted fluorene has lower oxidation potential (－5.45 eV) than the previous polyfluorenes (－5.80 eV).
