摘要

9,9- ji (huruoreniru) organic it possesses the -2,7- huruoreniru unit electro- luminescent the macromolecule and the electro- luminescent element which uses this are disclosed. Especially, this invention, enabled, 9,9- ji (huruoreniru) organic it possesses the -2,7- huruoreniru unit electro- luminescent offers the electro- luminescent element which uses the macromolecule, and the aforementioned electro- luminescent macromolecule by introducing the substitution huruoreniru basis into 9 rank of fluorene, blue color electro- luminescent as a macromolecule and a host material. The description above electro- luminescent the macromolecule, high solubility, has high thermal stability and high quantum efficiency, you can use as the host material of blue color, green color and red of high purity.
