“…In case of CV1 and CV2, the FT-IR spectra are mostly composites of those of c-ZrP and free dye, except for the absorption bands around the region 1,600-1,400 cm -1 , where these bands assigned to the CC stretching vibrations of the aromatic rings, appear in the spectrum of free CV dye. It can be concluded that, upon protonation these bands shift to higher frequencies, as in the case of porphyrins [17] and a-diimines [18]. Thus, the free CV dye has strong absorption at 1,585, 1,470, 1,364 and 1,173 cm -1 , whereas these bands almost disappeared in the intercalates.…”

Batch intercalation experiments have carried out using c-zirconium phosphate (c-ZrP) and one of its cationic surfactant forms (c-ZrP/SUR ? ) for removing crystal violet from aqueous solutions. The intercalation reactions have conducted along two different intervals of time (24 and 48 h). The intercalation process has followed up by X-ray diffractometry (XRD), UV-Visible and FT-IR spectrophotometries. Regarding c-ZrP, XRD patterns show that obtained phases are impure, even after 48 h of the reaction time at a maximum dye loading of 18%. On the other side, c-ZrP/SUR ? gives an impure phase after 24 h while a pure one (2.47 nm) is obtained after 48 h at a maximum dye loading of 19%. In both cases, the observed dye loading values are approximately equal to the one calculated by molecular modeling (ca. 20%). The used analysis approaches prove that dye uptake capacity is a function of the reaction time and inclination angle of the dye molecules inside the solid matrices, where the highest dye uptakes are observed with c-ZrP and c-ZrP/SUR ? after 48 h of the reaction time. This time (48 h) is long enough for the dye molecules to be sufficiently accumulated inside the interlayer regions, in such situation dye molecules are forced to stand up perpendicular to the inorganic layers. With respect to intercalation properties, the difference between c-ZrP and c-ZrP/SUR ? could be referred to the difference between their gallery heights (1.22 and 3.00 nm, respectively). The pre-intercalation of c-ZrP with the surfactant molecules assists the inclusion and intercalation of the huge dye molecules into the interlayer region.

The art of designing and synthesizing organic molecules has reached very high levels of sophistication, based on a relatively simple set of rules that guide both the invention and synthesis of new compounds. This set of rules is construed as the rational synthetic method of organic chemistry. As material chemists confronted to the task of building new solid structures with tailored chemical properties, we do inevitably need to develop some rational approach and to establish the corresponding set of rules allowing a realistic level of predictive knowledge in the construction of solid scaffolds. These conditions are reasonably accomplished by the use of layered salts of tetravalent transition metals, namely zirconium phosphate (ZrP). The placing of organic molecules between the layers of ZrP is quite straightforward, can easily be controlled and leads to enduring, solid materials where the confinement makes the organic molecules to show new properties at the supramolecular level. The chemistry of metal phosphates/phosphonates will be detailed in relation with the following topics: (i) molecular recognition, (ii) chemically driven porosity changes, (iii) chiral memory and supramolecular chirality, (iv) luminescence signalling, (v) photo-induced electron-transfer processes, (vi) hydrogen storage, (vii) confinement of drugs and (viii) metal uptake.
