conformers are connected into one-dimensional (1D) chiral-chains (ΔΔΔ-chain or ΛΛΛ-chain). Structural analyses disclose that the assembly fashion and chirality transfer in theses complexes are modulated by the supramolecularinteractions including N–H⋯F hydrogen bonds, intra- and inter-molecular π–πinteractions which are directed by the counter anions as well as additional aromatic molecules.
