“…In-situ hydrothermal synthesis methods have been used to provide isomorphic 57 incorporation of Fe into MFI zeolite structure, although reports to date have limited the 58 Si/Fe molar ratio to 100 (1 at%Fe) (Kritchayanon et al, 2006;Taniguchi et al, 2016). 59…”

Environmentally emerging micro-pollutant, caffeine, was mineralized (i.e., full degradation) by the isomorphic incorporation of Fe into silicalite-1 (mordenite framework inverted (MFI) structure zeolite) through a microwave synthesis method. The Fe incorporation conferred mesopore formation that facilitated caffeine access and transport to the MFI zeolite structure. Increasing the Fe content favored the formation of Fe(O) sites within the MFI structure. The catalytic activity for the degradation of caffeine increased as a function of Fe(O) sites via a Fenton-like heterogeneous reaction, otherwise not attainable using Fe-free pure MFI zeolites. Caffeine degradation reached 96% (TOC based) for zeolites containing 2.33% of Fe.

“…Silatrane is an organosilicate that has been become a great interest for the past few years to produce advanced materials, especially mesoporous materials via sol-gel process. 13 14 Wongkasemjit and her coworkers [15][16][17][18][19][20][21][22][23] have synthesized highly pure silatrane via the "Oxide One Pot Synthesis" process for producing mesoporous materials through the sol-gel process. The reaction of silatrane precursor with different surfactant templates provided variety of high-quality products, denoted by MFI, ZSM-5, and MCM-41.…”

Mesoporous silica materials with ordered structures were prepared from a silatrane precursor and a poly(amido amine) dendrimer porogen under the dilute acidic condition via the sol-gel process. With decreasing the concentration of the dendrimer and adding much water, the production of undesirable amorphous silica was diminished and spherical particles with smooth surface became in majority. Two kinds of crystal arrays were found to be produced in the silica particles. Although pore diameters were within sizes of shrank and extended dendrimers, center-to-center distance of template pores was different each other for two arrays, and the difference was close to a molecular length of silatrane. These results indicate that one molecule of silatrane constructed polysiloxane wall in the first array and origomeric silatranes formed wall in the second array. It was referred that the intrinsic (hydrogen bonding) character of hydroxyl groups in the hydrolyzed silatrane resulted in hydrogen bonded oligomers and reinforced the hydrogen bonding interaction with dendrimer porogen as well as electrostatic interaction, giving rise to two types of template arrays.

“…Further, owing to hydrolytically stable nature, it regulates the hydrolysis rate and condensation processes in the eld of sol-gel processes. Moreover, silatranes are also used as adhesive promoter and strong reducing agent for conversion in organic synthesis [21][22][23][24][25][26][27][28][29][30][31][32].…”

The present article includes the generation of aromatic Schiff base tethered organosilatranes via two step synthetic pathways starting from anthracene-10-carbaldehyde and 1H-indole-3-carbaldehyde. The synthesis was achieved by employing condensation reaction followed by transesteri cation methodology. The prepared organosilatranes containing aromatic schiff based ligands were structurally authenticated using spectroscopic techniques such as FT-IR, NMR and mass analysis. The prepared compounds were also scrutinized for in silico physiochemical properties via Molininspiration and ADMET software and the results revealed their good biological potential for drug discovery.
