Bisporphyrin-based flexible nanotweezers with various metals were synthesized and applied to the extraction of single-walled carbon nanotubes. Homo- and hetero-metallic bisporphyrins containing Co2+ were found to afford higher SWNT-extraction ability, while no or a little amount of SWNTs were extracted by bisporphyrins with other metals.
