## Description

- description: "Electron-deficient viologens are widely used as ligands or structure-directing
    agents (SDAs) to synthesize crystalline X-ray induced photochromic materials.
    Here, a new rational strategy of anion-directed folding a flexible cation (H2imb)2+
    ((H2imb)2+ = di-protonated 2,3-bis(imidazolin\x022-yl)-2,3-dimethylbutane) has
    been developed. Electron-donating Cl−and (ZnCl4)2− are used to direct folding
    a flexible electron-deficient (H2imb)2+ cation. Three complexes (H2imb)(NO3)2
    (1), (H2imb)Cl2·H2O (2), and (H2imb)ZnCl4 (3) have been synthesized in which (H2imb)2+
    crystallize in an anti-conformation, 88.8°-gauche, and 51.8°-gauche, respectively.
    In contrary to X-ray silent complex 1, X-ray induced photochromism has been achieved
    in both complex 2 and 3. An intermolecular charge-transfer mechanism has been
    elucidated and the anion directed \r\nfolding of (H2imb)2+ has been validated
    to be critical to yield colored long-lived charge-separated states.\r\n"
