Synthesis of Tetraphenyl-Substituted [12]Cycloparaphenylene: Toward a Rationally Designed Ultrashort Carbon Nanotube

摘要

The fi r s t ph e n y l - s u b s t i t u t e d [ n ] -ncycloparaphenylene (1) has been synthesized. The preparationnof this structure addresses several challenges toward a morenelaborate phenyl-substituted [n]cycloparaphenylene (2), anmolecule that may lead to the homogeneous synthesis ofnarmchair carbon nanotubes.
