LIGHT EMITTING POLYMER WITH CYANO AND CARBAZOLE THEREOF AND LIGHT EMITTING DEVICE USING SAME

摘要

PURPOSE: A light emitting polymer is provided to enable the dissolution in an organic solvent while emitting the fluorescent light and to ensure good luminous efficiency by smoothening electron transportation. CONSTITUTION: A light emitting polymer is represented by chemical formula 1. In chemical formula 1, R1-R8 are independently C4-C10 linear alkyl or a compound represented by chemical formula 2; at least one of R1~R8 is the compound represented by chemical formula 2; k and m are 0.5; and n is an integer of 5~100. In chemical formula 2, R9 is C4-C10 linear alkyl.
