SYNTHESES AND OPTOELECTRONIC PROPERTIES OF A HEXA-ARMED FLUORENE-BENZENE COPOLYMER BASED ON 2,4,6,8,10,12-HEXABENZYL-2,4,6,8,10,12-HEXAAZAISOWURTZITANE CAGED-CORE

Received Date: 23 April 2008
Revised Date: 12 June 2008

A novel kind of hexa-armed fluorene-benzene copolymer based on a hexaazaisowurtzitane core was synthesized through Suzuki coupling polycondensation. The introduction of this bulky caged-core could not only enhance the photoluminescence quantum efficiency, but also improve the electroluminescence properties, especially suppress the common green-color emission of polyfluorenes (PFs) material during device operation. These features can be attributed to the successful suppression of PF’s chain aggregation which profits from the introduction of the bulky hexaazaisowurtzitane core and the design of multi-armed architecture.
