“…Such behavior can be assigned to the difference between the dipole moments of trans-and cis-azobenzene isomers: the film containing the more polar cis-isomer will become more hydrophilic, while the trans-isomer makes the surface hydrophobic. Wang et al [43] have fabricated optically transparent thin films with photochromic properties by means of cointercalation of azomethine-H anions (AMH) and 1-pentanesulfonate (PS) with different molar ratios into the nanogallery of a ZnAl-LDH. XRD and SEM show that the film exhibits welldefined c-axis orientation.…”

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.

“…The band located at 465 nm is due to the S 0 state of the trans-keto tautomer, and a 5 nm blue shift due to the changed weak polar microenvironment can be observed. The absence of syn-enol form indicates the inhibition of the syn-enol/anti-enol isomerization in the [174] 2D confined environment. As a result, the trans-keto tautomer of AMH is less stable in the 2D confined environment, and relaxed back isomerization is more easily to take place.…”

“…Wang et al have studied the photoisomerization process of a kind of Schiff base (azomethine-H anions, AMH) assembled LDH system [174]. Generally, after the excitation of the initial enol (anti-enol) tautomer, the excited-state intramolecular proton transfer (ESIPT) occurs for AMH, leading to the excited keto tautomer (cis-keto or its zwitterionic form), exhibiting a characteristic Stokes fluorescence band.…”

N-Salicylidene p-aminobenzenesulfonate salts were prepared by in situ condensation of p-aminobenzenesulfonate diallylammonium salt and salicylaldehyde. Modulation of thermo- and photochromism was achieved by varying the alkyl chain length of the diallylammonium counter-cation. A structural-optical properties investigation reveals that both crystal packing and dihedral angle between aromatic rings of the N-salicylidene aniline switch are not sufficient to predict the occurrence of photochromism in the solid state. The available free space around the N-salicylidene p-aminobenzenesulfonate, in addition to the flexibility of the nearby environment, is shown to be of major importance for the cis→trans isomerisation to occur as well as for the stabilisation of the trans-keto form. Emergence of photochromic properties was determined from the diallylhexylammonium cation within the series of investigated counter-cations. High stability is observed for the trans-keto form of one polymorph of N-salicylidene p-aminobenzenesulfonate diallylhexylammonium salt (k = 2.4×10(-7) s(-1)).
