Photochemical Addition of Ethers to C 60 : Synthesis of the Simplest [60]Fullerene/Crown Ether Conjugates

Easy crowning for [60]fullerene : The simplest and hitherto elusive C 60 /crown ether conjugates have been prepared through an effective free‐radical approach. This approach includes the activation of the otherwise unreactive α ‐CH bond in a series of structurally diverse mono‐ or polyethers and sulfides. This facile method provides an expedient entry into a novel class of fullerene‐based materials.
