We have developed novel multifunctional carbazole oligomers and hyperbranched polymers. Carbazole oligomers show better photorefractive performance than those of main-chain polymers and provide molecular-level tuning. In order to merge the advantages for oligomers and polymers, we have developed hyperbranched polymers with oligomer units. This new hyperbranched polymer showed red-shifted fluorescence which can be applied to multifunctional electroluminescent materials as a new class of hyper-structured photonic molecules.
