  • Self-Assembly Behavior Shifting to Crystal Formation of Chiral Macrocyclic Tetraimines
    Crystal Growth & Design, 2019
    Co-Authors: Masahide Tominaga, Masatoshi Kawahata, Tsutomu Itoh, Kentaro Yamaguchi

    Abstract:

    The enantiopure macrocyclic tetraimines containing Adamantane moieties (1, 2) were synthesized from (R,R)- or (S,S)-1,2-cyclohexanediamine and a disubstituted Adamantane Derivative having salicylal…

    Abstract:

    The enantiopure macrocyclic tetraimines
    containing Adamantane moieties
    (1, 2) were synthesized from (R,R)- or (S,S)-1,2-cyclohexanediamine
    and a disubstituted Adamantane Derivative having salicylaldehyde in
    moderate yield. Single crystals (1a) were obtained from
    a methanol/chloroform mixture and 1. X-ray crystallographic
    analysis revealed that the macrocycles had a rhomboidal structure
    and were arranged into a molecular network bearing layer structures
    through CH···O and CH···π interactions.
    Racemic crystals (1·2-a) were formed from crystallization of 1 and 2 in a 1:1 stoichiometry. The macrocycles had a rhomboidal framework
    with a longer axis, and 1 and 2 were alternatively
    aligned into the molecular network composed of columnar structures
    by CH···π and CH···O interactions.
    Macrocycle 1 self-assembled into spheres, and their fused
    fibrous and network aggregates, and eventually were translated into
    crystals. Meanwhile, the mixing of both enantiomers 1 and 2 at a ratio of 1:1 afforded racemic crystals by
    way of similar self-assembled structures under identical conditions;
    however, the rate of crystal formation was faster than that of 1
