Silver(<scp>i</scp>) N-heterocyclic carbene-bridged calix[4]arene analogues as efficient [60]fullerene receptors

Abstract

Two silver(I) N-heterocyclic carbene-bridged calix[4]arene analogues 4 and 5 were synthesized by a fragment-coupling approach; the preliminary inclusion properties of 5 with [60]fullerene shows that it is a novel efficient [60]fullerene fluorescent sensor.
