“…Second, for applications in the environmental and biomedical fields, Sun et al reported the fabrication of an optical chemosensor based on a 1‐amino‐8‐naphthol‐3,6‐disulfonic acid sodium (H‐acid)‐intercalated LDH film that can recognize heavy metal ions. Obtained by the electrophoretic deposition method, the H‐acid/LDH film displayed a thickness of 1 nm and possesses a good c ‐orientation of LDH microcrystals . Fluorescence detection for Hg 2+ in aqueous solution performed at pH 7.0 revealed a linear response range from 1.0 × 10 −7 to 1.0 × 10 −5 mol L −1 and a detection limit of 6.3 × 10 −8 mol L −1 .…”

International audienceHybrid materials based on layered double hydroxides (LDHs) exhibit great potential in diverse fields such as health care, polymer composites, environment, catalysis, and energy generation. Indeed, the compositional flexibility and the scalability of LDH structures, their low cost, and their ease of synthesis have made hybrid LDHs extremely attractive for constructing smart and high-performance multifunctional materials. This review provides a comprehensive and critical overview of the current research on multifunctional hybrid LDHs. Organic–inorganic hybrid LDHs, intercalated and surface-immobilized structures, are both specifically addressed. The new trends and strategies for hybrid LDH synthesis are first described, and then the potential of the latest hybrid LDHs, polymer LDH nanocomposites, and LDH bio-nanocomposites are presented. Significant achievements published from ≈2010, including authors' results, which employ hybrid LDH assemblies in materials science, medicine, polymer nanocomposites, cement chemistry, and environmental technologies, are specifically addressed. It is concluded with remarks on present challenges and future prospects

“…As a consequence of this pollution, mercury can accumulate in the human body, which causes a wide variety of diseases, even in a low concentration, such as digestive, kidney, and neurological disorders. Sun et al [65] have reported that an optical thin film can serve as chemosensor based on 1-amino-8-naphthol-3,6-disulfonic acid sodium (H-acid) intercalated LDH. The H-acid/LDH film chemosensor was immersed into Hg 2+ aqueous solutions with different concentrations at pH value 7.0 for 10 min then was washed thoroughly, and dried at 60 ∘ C for 20 min.…”

The assembly of photofunctional molecules into host matrices has become an important strategy to achieve tunable fluorescence and to develop intelligent materials. The stimuli-responsive photofunctional materials based on chromophores-assembled layered double hydroxides (LDHs) have received much attention from both academic and industry fields as a result of their advantages, such as high photo/thermal stability, easy processing, and well reversibility, which can construct new types of smart luminescent nanomaterials (e.g., ultrathin film and nanocomposite) for sensor and switch applications. In this paper, external environmental stimuli have mainly involved physical (such as temperature, pressure, light, and electricity ) and chemical factors (such as pH and metal ion); recent progress on the LDH-based organic-inorganic stimuli-responsive materials has been summarized. Moreover, perspectives on further development of these materials are also discussed.

“…A certain amount of fluorescence molecules have been applied (such as BTBS [101], calcein [109], and 1-amino-8-hydroxy-3,6-disulfonaphthalene (H-acid) [157]) as probes for the detection of HMIs (such as mercury ion). Taking BTBS/ LDH system as an example, fluorescence emission spectrum shows a monotonic increase with n at ca.…”
