LIGHT EMITTING POLYMER CONTAINING ALKYLIDENEFLUORENE AND ELECTROLUMINESCENCE DEVICE USING THE SAME

摘要

PURPOSE: An organic light conversion polymer and an organic photovoltaic device using the same are provided to optimize energy level by increasing oxidation stability and planarity. CONSTITUTION: An organic light conversion polymer includes n-type molecule having electron-withdrawing properties and alkylidene fluorene as backbone. The organic light conversion polymer is represented by chemical formula 1. Here, R indicates hydrogen, C1-25 alkyl, C1-25 alkoxy, thiophene which is substituted with hydrogen, C1-25 alkyl or C1-25 alkoxy, selenophene which is substituted with hydrogen, C1-25 alkyl or C1-25 alkoxy radical, pyrrole which is substituted with hydrogen, C1-25 alkyl group or C1-25 alkoxy radical, arylene which is substituted with hydrogen, C1-25 alkyl or C1-25 alkoxy, aryl which is substituted with hydrogen, C1-25 alkyl or C1-25 alkoxy, thiazole which is substituted with hydrogen, C1-25 alkyl or C1-25 alkoxy, and is selected from C10-24 aryl having the fused integrated aromatic ring compound. The spacer is selected from thiophene which is substituted with hydrogen, C1-25 alkyl or C1-25 alkoxy, selenophene which is substituted with hydrogen, C1-25 alkyl or C1-25 alkoxy, thiazole which is substituted with hydrogen, C1-25 alkyl group or C1-25 alkoxy radical, and is selected from C10-24 aryl having the integrated aromatic ring compound.
