The synthesis and characterization of novel homochiral oligomacrocycle species composed of enantiomerically-pure tetraphenylene were described. Structural studies showed that the macrocyclic molecule possessed a helical chiral cavity, which exhibited unique and efficient recognition affinity towards fullerene C-76 in toluene, as demonstrated by UV-vis titration experiments. The binding results were also interpreted through semi-empirical calculations. (C) 2017 Elsevier Ltd. All rights reserved.
