Fabrication of High‐Resolution 4,82‐type Archimedean Nanolattices Composed of Solution Processable Spin Cross‐Over Fe(II) Metallosupramolecular Polymers

This paper presents the synthesis of two highly soluble Fe(II) metallosupramolecular polymers with two counter anions from a novel back‐to‐back coupled hybrid ligand. The spin cross‐over (SCO) temperature of polymers with BF4 and ClO4 counter anions is T1/2 = 313 K and T1/2 = 326 K, respectively. By following the top‐down approach, one of the polymers (with ClO4 counter anion) is successfully solution processed using a lithographically controlled wetting technique to create laser readable high‐resolution Archimedean (4,82) nanolattices (consist of diamagnetic octagons and SCO squares). The thickness and top area of each SCO square are ≈75 nm and ≈2 × 2 μm2, respectively. image
