A Ni(0)-mediated coupling reaction of a 1,8-dibromopyrene gave a series of cyclic pyrene oligomers CPn up to nonadecamer. CP5 and CP7 represent a unique class of asymmetric compounds with no stereogenic chiral centers in terms of their global chirality, which are achieved because of an odd number of pyrenes.
