Title:
LADDER-TYPE BLUE LIGHT-EMITTING POLYMER WITH EXCELLENT THERMAL STABILITY
Document Type and Number:
Japanese Patent JP2004143426
Kind Code:
A
Abstract:
To provide a ladder-type blue light-emitting polymer brought to have excellent thermal stability by combining a blue light-emitting monomer with a polymer main chain of the polymer, subsequently polymerizing the monomer or polymerizing after adding fluorene to styrene monomer.
The blue light-emitting polymer has ≥400°C high glass transition temperature and 5% mass reduction temperature. Therefore, the polymer is not only used as a blue light-emitting material for display but applied as a light-emitting case of domestic electric appliances and a light-emitting case for cellular phones through blends with resin polymers.
