“…, suggesting that they might be protonated to achieve charge-balance and to enhance the interaction by establishment of H-bonds between the proton (attached to N) and the terminal O in PO 3b O t units. We should note that most of these low-dimensional frameworks have traditionally been obtained under solvothermal conditions, but rarely crystallize in aqueous gels [39,[41][42][43][44] as our materials.…”

A new strategy for the synthesis of three new un-assemblable metastable AlPO-based layered framework materials is reported. By using organic molecules with aromatic rings that tend to self-assemble in water solution by establishing π-π type interactions, three new AlPO layered frameworks have been produced with benzylpyrrolidine and its meta-and para-fluorinated derivatives. These new layered materials occlude an extremely large amount of organic material. Interestingly, UV-Visible fluorescence results show that the molecules occluded within the frameworks form supramolecular aggregates, and consequently the crystallization of these structures is strongly dependent on the self-assembly ability of the organic *Manuscript Click here to download Manuscript: Manuscript-LGH-rev.docx Click here to view linked References molecules in water. As a consequence, the ortho-fluorinated derivative, which shows the lowest trend to aggregate in water, is not able to produce a stable self-assembled AlPO framework.The self-assembly of the organic molecules within the frameworks driven by relatively weak π-π type interactions between the aromatic rings combined with a poor H-bond interaction of the heterocyclic tertiary N with terminal PO groups enable a simple un-assembly (delamination) process of the structures by treating the samples in water.

Intersecting Twelve-Ring Channels. -The new title compound is hydrothermally synthesized from an aqueous mixture of Al2O3, H3PO4, and piperazine (autoclave, 180°C, 3 d) and its structure is determined by single crystal XRD. It crystallizes in the trigonal space group R3 with Z = 9. The strict alternation of AlO 4 , PO 2 (=O) 2 , and PO 3 (=O) tetrahedra via bridging oxygen atoms results in a three-dimensional open-framework with helical chains forming multi-directional intersecting 12-ring channels. 22 mol% of the protonated piperazinium cations can be exchanged by Na + cations. -(TONG, X.; HUANG, P.; LU, H.; YAN*, W.; YU, J.; XU, R.; Inorg.
