Abstract:

  Sensitization is of importance to the near-infrared (NIR) emission of lanthanide ions and the solar energy conversion in photovoltaics. In lanthanide complexes, light-harvesting materials (ligands) are used to transfer the energy to the metal center to generate unique long-wavelength emission for sensitive detection of tumor markers. In solar energy conversion, light-harvesting materials (dyes) are used to absorb the sunlight and inject electrons to the semiconductor for the production of electricity. One common challenge in these two seemingly unrelated sensitization processes is the narrow absorption of the ligands or dyes in the visible region, leading to their poor performance. In this seminar, I will present our recent studies in these two areas with more focus on molecular design. The synthesis, characterization and performance of the new materials, especially porphyrin-based materials will be covered. The future research directions will also be discussed.
