Photoinduced Energy and Electron Transfer of Polyelectrolytes for the Use of Solar Fuels and Biosensor |
| 초록 |
Photoinduced energy electron transfer processes are widely utilized in every aspect of photosynthesis and optical biosensor. The work aims to understand mechanisms and dynamics for the photoprocesses in colloidal solution and at the interfaces of mesoporous structured semiconductor and metal nanoparticle. We reported a series of polystyrene-based light harvesting polymers with pendant Ru chromophores (PS-Ru) and conjugated poly(phenylene ethynylene) (PPE) derivatives for the use of solar energy conversion and optical biosensor. The talk will present the findings of photophysical properties of PS-Ru coated mesoporous structured TiO2 nanoparticles and the quenching process of PPE polymer-Au nanoparticle pairs showing high Ksv ~ 1012 M-1, that enable sub-picomolar sensitivity in highly efficient polymer-based optical biosensors. |
