Lanthanide Materials Through Fusion Chemistry To Advanced Supramolecular Materials Towards Tomorrow’s Information Technology |
| 초록 |
We have developed novel lanthanide-cored supramolecular systems with highly efficient light-harvesting dendritic arrays for integrated planar waveguide-typed amplifiers as well as light-emitting diodes. The supramolecular ligands have been designed and synthesized to provide enough coordination sites for the formation of stable lanthanide-chelated complexes. Lanthanide(III) ions were encapsulated by the supramolecular ligands such as porphyrins, naphthalenes and macrobicyclics. For getting a higher optical amplification gain, also, the energy levels of the supramolecular ligands were tailored to maintain the effective energy transfer process from supramolecular ligands to lanthanide(III) ions. Key important parameters for emission enhancement were examined. Also, efficient energy transfer pathways for the sensitization of lanthanide ions by supramolecular ligands in lanthanide-cored supramolecular systems were investigated for the first time to my best knowledge. Furthermore, to maximize the light-harvesting effect, new aryl ether-functionalized dendrons as photon antennas have been incorporated into lanthanide-cored supramolecular systems. In this presentation, molecular design, synthesis and photophysical studies of novel lanthanide-cored supramolecular systems with highly efficient light-harvesting dendritic arrays towards tomorrow’s information technology will be discussed. |
