Annihilation-limited Long-range Exciton Transport in High-mobility Conjugated Copolymer Films

Kavli Affiliate: Graham Fleming | Summary:A combination of ultrafast, long-range and low-loss excitation energy transfer from the photo-receptor location to a functionally active site is essential for cost-effective polymeric semiconductors. Delocalized electronic wavefunctions along π-conjugated polymer backbone can enable efficient intrachain transport, while interchain transport is generally thought slow and lossy due to weak chain-chain […]
