A series of new fluorene-based π-conjugated polymers having coumarin derivatives as part of dendritic side chains were designed and prepared using the Suzuki–Miyaura cross-coupling reaction. A new coumarin derivative bearing a heptyl side chain for solubility was utilized to ensure solubility of the final polymers. It was found that fluorescence resonance energy transfer (FRET) from the coumrains to the polyfluorene backbone was efficient, especially for the polymers decorated with lower-generation dendrons. Each of the polymers was found to interact strongly with the surface of single-walled carbon nanotubes (SWNTs) in THF, and their ability to selectively disperse specific SWNT chiralities was investigated. Photoluminescence studies revealed that the strong polymer emission is efficiently quenched in the corresponding supramolecular complexes with SWNTs. This high quenching efficiency indicates that the coumarin–polymer FRET system can be supramolecularly bound to the surface of (SWNTs to produce an energy transfer system in which the energy absorbed by the donor coumarin chromophores is channeled to the SWNTs.
