Oriented calix[6]arene-based pseudorotaxanes and rotaxanes where the axial component bears a terpyridine ligand as a stopper positioned at the upper rim of the calixarene have been synthesized. The binding ability of the terpyridine unit present in the axle toward zinc salts is affected by the presence of the wheel, its distance with respect to the calix[6]arene upper rim, and the nature of the counterion
已经合成了定向杯[6]芳烃基假轮烷和轮烷,其中轴向组分带有三联吡啶配体作为位于杯芳烃上缘的塞子。存在于轴中的三联吡啶单元对锌盐的结合能力受轮的存在、轮与杯[6]芳烃上缘的距离以及所用锌盐的抗衡离子的性质的影响。三联吡啶单元的金属配位改变了假轮烷和轮烷中轮内轴的 4,4'-联吡啶单元的电化学行为。
