Synthesis and Photophysical Studies of Luminescent Lanthanide(III)-cored Complexes Based on Alkyne Substituted Diphenylquinoxaline Dendritic Derivatives |
| 초록 |
The novel lanthanide(III) complexs based on alkyne substituted diphenylquinoxaline dendritic ligand were designed and synthesized to enhance the luminescence intensity of Er3+ ions for photonic applications and to provide enough coordination sites for the formation of stable Er(III)-chelated complexes. The alkyne substituted diphenylquinoxaline ligand was used as photon antenna for the efficient light harvesting effect by improving the low quantum yield and molar-extinction coefficient of the well-known aryl-ether dendron. These novel complexs are predicted to enhance the energy transfer efficiency more by a liner structure than by tilted structure. Er3+-cored supramolecular complex based on alkyne substituted diphenylquinoxaline ligand exhibited strong near-IR emission. |
