ABSTRACTInterleaved monomers and polymers between the sheets of layered double hydroxide (LDH) (hydrotalcite-type) materials are considered as carbonaceous source. After a charring process constituted of a carbonisation and a subsequent demineralisation, carbonaceous materials of interesting textural properties were obtained. The initial preparation of the polymer LDH hybrid phase was found to strongly orientate the textural characteristics, microporous volume and creation of mesoporosity. Several methods to assess the microporosity, t-plot, αs and Dubinin-Astakhov, are compared. Specific surface area as high as 2300 m2/g measured by BET method and microporous volume of 1.07 mL/g were obtained. The carbonaceous materials tested as supercapacitor in acidic medium present capacitances in the range 60 - 120 F/g associated to a good behavior in cycling.

Macrocyclic Molecules

In the present review, we show how the chemical variability of phthalocyanines allowed to synthesize a broad range of hybrid materials. The combination of phthalocyanines or related derivatives with polymers or carbonaceous materials led to efficient chemical sensors. It is shown how the incorporation of macrocyclic molecules in hybrid materials highly modifies the structural and morphological characteristics of the materials. Rugosity, specific surface and porosity being key parameters in the analyte-sensing material interactions, these modifications highly improve the performance of chemical sensors. This is the reason why they are particularly promising materials for the development of new chemical sensors, associated with electrochemical, conductometric or optical transducers.

ABSTRACTIncorporation and subsequent stabilization of organic molecules into layered double hydroxide are investigated. Through two types of hybrid materials, organic dyes and aniline-based monomers interleaved between LDH materials of cation composition Zn2Al and Cu2Cr respectively, it is shown that the effect of the constrainment is revealed by the interactions different according to the molecule size and stacking as exemplified by dye molecules, orange 6 and green 25 acids and two aniline-based monomers, m-amino-4-benzenesulfonic and 3-aniline-1-propanesulfonic acids.
