A high-refractive index polymer of polyimide was prepared by imidization in removing water. Initially, the poly(amic acid) (PAA) was simply and quickly synthesized by the reaction between 4,4'-(hexafluoroisopropylidene)diphthalic anhydride (6FDA) and bis(3-aminophenyl) sulfone (3DDS). Next step, PAA was transformed to polyimide (PI). Finally, the polyimides were connected together to form network by cross-linking agent. This polymer network was characterized by FT-IR, GPC, TGA, transmittance and refractive index. With the high-refractive-index and thermal, flexible characteristic, this novel polyimide could be potential material to be utilizing as the outcoupling layer, the hole transport layer or the emitting layer in optoelectronic device applications. |
