“Optimization of the molecular design of a fluorinated wide bandgap polymer for non-fullerene solar cells” |
| 초록 |
Fluorine (F) substitution on conjugated polymers has been proved to be the prominent way to fine-tune the frontier molecular orbitals and back bone planarity through inter/intramolecular non-covalent S···F and/or H···F interactions. We synthesized a series of fluorinated wide band gap polymers with a structural variation to understand the influence of molecular design on photovoltaic properties. We systematically studied effect of these structural modification on the molecular interactions and performances by analyzing and comparing DFT calculations, optical-electrochemical analysis, molecular ordering and photovoltaic properties of the resulting polymers. The structure-property correlations from this work provide useful insights for developing wide-band-gap polymers with low-lying highest occupied molecular orbitals. |
