“…Chistyakov et al [ 20 ] developed films based on β-diketophosphazene and amines to investigate their properties. The aryloxycyclotriphosphazene containing a diketo functional group was synthesized through the reaction of hexakis(4-chloromethylphenoxy) cyclotriphosphazene with sodium acetylacetonate.…”

“…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 ].…”

Two-dimensional layered coordination polymers based on the hetero-substituted 3-chloro-6-cyano-2,5-dihydroxybenzoquinone ligands, hereafter ClCNAn2− anilate, and LnIII ions (Tb and Eu) are reported. Compounds 1 and 2, formulated as Ln2(ClCNAn)3(DMSO)6 (LnIII = Tb, 1; Eu, 2), and their related intermediates 1′ and 2′, formulated as Ln2(ClCNAn)3(H2O)x·yH2O (x + y likely = 12, Ln = Tb, 1′; and Eu, 2′), were prepared by a conventional one-pot reaction (the latter) and recrystallized from DMSO solvent (the former). Polyhydrated intermediates 1′ and 2′ show very similar XRPD patterns, while, despite their common stoichiometry, 1 and 2 are not isostructural. Compound 1 consists of a 2D coordination framework of 3,6 topology, where [Tb(DMSO)3]III moieties are bridged by three bis-chelating ClCNAn2− ligands, forming distorted hexagons. Ultrathin nanosheets of 1 were obtained by exfoliation via the liquid-assisted sonication method and characterized by atomic force microscopy, confirming the 2D nature of 1. The crystal structure of 2, still showing the presence of 2D sheets with a “hexagonal” mesh and a common (3,6) connectivity, is based onto flat, non-corrugated slabs. Indeed, at a larger scale, the different “rectangular tiles” show clear roofing in 1, which is totally absent in 2. The magnetic behavior of 1 very likely indicates depopulation of the highest crystal-field levels, as expected for TbIII compounds.

“…10,14 Recently, new kinds of polymeric matrix for EHSMs have gained great attention to researchers. Than is, polyphosphazenes (with inorganic backbone of "─P═N─") can be maneuvered as EHSMs by introducing different substituents to obtain different functional polymers such as higher hydrophobicity property, 18 higher glass transition temperature and higher char yield, 19 and low water absorption and solubility. 20 Poly(diaryloxyphosphazenes) (PDPP), an inorganic-organic macromolecule with substituent of aryloxy group is anticipated to serve as an effective alternative polymeric matrix for EHSMs due to its high char yield, excellent flame retardant property, low heat release capacity and low-density smoke.…”

Elastomeric heat shielding materials (EHSMs) are necessary to protect combustion chambers of solid rocket motors during their working.Poly(diaryloxyphosphazene) (PDPP) elastomers own inherent thermal stability and flame retardancy because the backbone of alternating phosphorus and nitrogen atoms can be a novel promising polymer matrix toward EHSMs. The present study deals with the development of a novel PDPP based EHSMs with several different fibrous reinforcements, including Kevlar, polyimide, and carbon short fibers. It is found that PDPP/Kevlar composites show outstanding tensile strength and ablation resistance because of their strong interfacial bonding between matrix and fibers which benefits from the possible network of intermolecular hydrogen bonds. PDPP/carbon composites produce a compact charred layer due to their high char yields of carbon fibers. These results improve the understanding of the role of polyphosphazenes with different kinds of fibers on ablation mechanisms, which enable the possibility to exploit intrinsic properties of polyphosphazenes.
