Summary of materials obtained by supramolecular organizations of zeolite L crystals. (a) Randomly oriented zeolite L crystals in a polymer. Photographic images of zeolite L-polymer hybrid materials prepared from crystals loaded with either red or violet dyes (Hostasol Red GG or Ox, resp.) [48, 49]. (b) Nematic phase arrangement. Left: SEM and fluorescence microscopy image of Py-zeolite L crystals aligned in a stretched PVC plastic film [77]. (c) Hexagonal arrangement. The dye-zeolite L crystals are organized by a surface-tension-driven self-assembly process on a PDMS/PS film (SEM and fluorescence microscopy image are shown) [78]. (d) Monolayers of standing zeolite L crystals. Left: SEM image of a monolayer. Right: fluorescence microscopy image of a monolayer loaded with Py [45–47]. (e) Nanofibers with embedded zeolite L. Left: SEM image of nanofiber with embedded zeolite L crystals. The crystals are oriented along the fiber axis. Right: Fluorescence image of a PEO/DDT nanofiber (blue emission) with embedded Ox-zeolite crystals (red sparks) [79]. (f) Chain-like assemblies of zeolite L crystals. Right: SEM image of zeolite crystals linked together by modifying the channel entrances with a cationic stopcock (D291) and corresponding fluorescence microscopy image [77]. (g) Assembly of zeolite L/bacterium in PBS buffer solution and self-assembly of two bacteria with functionalized 1-m zeolite L as the junction [80].
