Luminescent Coatings Based on (3-Aminopropyl)triethoxysilane and Europium Complex β-Diketophosphazene

Abstract

The reaction of β-diketophosphazene with the europium (III) salt synthesized the corresponding metal complex which was structured with (3-aminopropyl)triethoxysilane and treated with dibenzoylmethane for additional coordination of europium atoms. The polymer thus obtained exhibits luminescence with a maximum of 615 nm, which is characteristic of europium. The polymer is thermally stable up to 300 °C, the coating based on it has a contact angle of 101°, and the adhesive strength of the coating to non-finished glass (according to ISO 2409: 2013) is 1 point.

Progress in the Field of Cyclophosphazenes: Preparation, Properties, and Applications

“…Maslennikova et al [ 96 ] developed a polymer through the reaction of β-diketophosphazene with europium(III) salt. The synthesized metal complex was further structured by incorporating (3-aminopropyl)triethoxysilane and treated with dibenzoylmethane to facilitate additional coordination of europium atoms.…”

Terbium and Europium Chlorocyananilate-Based 2D Coordination Polymers

“…Lanthanide-based Coordination Polymers (Ln-CPs) and Metal-Organic Frameworks (Ln-MOFs) have attracted considerable interest in material science thanks to their peculiar supramolecular architectures (extending in one, two or three dimensions: 1D, 2D and 3D), their versatile optical properties in the visible (Eu III and Tb III ) [ 1 , 2 , 3 ] and near-IR (NIR, for Nd III , Er III and Yb III ) regions, and also their unique magnetic (Ho III , Dy III and Tb III ) properties, due to their intrinsically high magnetic anisotropy, at the origin of interesting magnetic phenomena such as hard magnets or single-molecule magnets. By virtue of these features, they find applications in several applied fields, ranging from telecommunication and data storage to drug delivery, sensing and catalysis [ 4 , 5 , 6 , 7 ].…”

Intermolecular Interactions in 3-Aminopropyltrimethoxysilane, N-Methyl-3-aminopropyltrimethoxysilane and 3-Aminopropyltriethoxysilane: Insights from Computational Spectroscopy

“…It finds applications in industries like textiles, paints, and plastics, where improved surface properties are desired. The same applies in the biomedical and pharmaceutical fields, as the surface of biomaterials, such as implants or drug delivery systems, are used to improve biocompatibility, reduce immunogenicity, and enhance the interaction with biological tissues (see, e.g., [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]).…”

“…In this context, APTES was used for improving the fire resistance of surface-coated Araucaria angustifolia (Brazilian pine tree) wood [12] and to enhance the heat resistance properties of epoxy composites to high temperatures [13]. In this field, more recently, it has been used to prepare co-polymers to coordinate with Eu 3+ emissive complexes without affecting lanthanide's emission (615 nm), making it stable up to 300 • C [14]. In a study, APTES and MAPTS were used to derivatize the surface of mesoporous alumina towards its use in the removal of iodine under a radioactive setting for safe geological disposal of radioactive nuclei [15].…”
