Cover Picture: Ordered Ultrathin Films of Perylene Anions and Layered Double Hydroxide Using Exfoliation-coassembly Method (Chin. J. Chem. 9/2014)
The cover picture shows an ordered layered double hydroxide (LDH)-based organic-inorganic supramolecular hybrid material. An exfoliation-coassembly approach has been developed for the construction of ultrathin film (UTF) materials based on the layer-by-layer assembly of layered double hydroxide (LDH) nanosheets and perylene anions with the polyanions (such as poly 4-styrene sulfonate and poly vinyl sulfonate) as carriers. Due to the highly ordered supramolecular structure, the UTFs present polarized luminescence with the high emissive anisotropy. Such exfoliation-coassembly strategy can be extended to other similar systems to develop various LDH-based luminescent film materials. More details are discussed in the article by Yan et al. on page 859–864.
