“…[74] Recently, it has been revealed that complex atranes offer advantages for achieving better functionalizations with organic groups. Mutneja et al [75] explored the superiority of the silatranyl moiety as an anchoring unit over its trialkoxysilyl analogue for covalent grafting of mesoporous silicas. Furthermore, the inclusion of silatranyl moieties aids in the dispersion of silica particles by releasing triethanolamine during hydrolysis.…”

“…Silatranyl moieties with various organic groups have been utilized as hydrolytic precursors for post-functionalization of both massive and porous silicas. [75][76][77] Furthermore, in some cases, the silatranil entity has been used to generate the siliceous component through its hydrolysis without any other silica source. [78] These materials containing Schiff bases as organic groups, have been applied for the recognition, quantification, and absorption of different metals.…”

The use of triethanolamine in the preparation of materials has been a fertile area of research during the last decades. It is used in sol‐gel synthesis because of its ability to regulate pH, act as a structure‐directing agent, and form atrane complexes with a wide variety of elements. The atranes harmonize the hydrolysis and condensation processes of inorganic species with their interaction with surfactant molecules or micelles for the obtention of homogeneous materials. This review describes the basic principles of the formation of atrane complexes and their use in material synthesis, followed by a compilation of the main examples found in the bibliography. These materials include pure and doped silicas by using micelles as porogen species (MCM‐41, SBA‐15, UVM‐7, etc.), or without using template agents (TUD‐1, UVM‐11, etc.), non‐silica oxides (Al2O3, TiO2, ZrO2, etc.), mesoporous phosphates and phosphonates, zeotypes (zeolites, aluminophosphates or silicoaluminophosphates, and layered double hydroxides. The atrane route shows a versatile approach for the preparation of these materials with up to three elements simultaneously. The focus of the review centers on the synthesis of the materials and the discussion of their main applications. These examples enrich with a discussion about the future perspective of the topic.

“…In contrast, dyes functionalized with silanes (silatranes) can provide fixation through the formation of strong covalent bonds (see Scheme 3 ; see Refs. [ 70 , 71 , 72 , 73 ] and literature cited therein). At the same time, they possess low toxicity and high stability.…”

3-Aminopropylsilatrane and Its Derivatives: A Variety of Applications

et al. 2022

Silatranes arouse much research interest owing to their unique structure, unusual physical–chemical properties, and diverse biological activity. The application of some silatranes and their analogues has been discussed in several works. Meanwhile, a comprehensive review of the wide practical usage of silatranes is still absent in the literature. The ability of silatranes to mildly control hydrolysis allows them to form extremely stable and smooth siloxane monolayers almost on any surface. The high physiological activity of silatranes makes them prospective drug candidates. In the present review, based on the results of numerous previous studies, using the commercially available 3-aminopropylsilatrane and its hybrid derivatives, we have demonstrated the high potential of 1-organylsilatranes in various fields, including chemistry, biology, pharmaceuticals, medicine, agriculture, and industry. For example, these compounds can be employed as plant growth biostimulants, drugs, optical, catalytic, sorption, and special polymeric materials, as well as modern high-tech devices.
