Perfluorinated 1H-indazoles and hydrotris(indazol-1-yl)borates. Supramolecular organization and a new synthetic procedure to form scorpionate ligands

This paper describes the syntheses and full characterization of perfluorinated 1H-indazoles 2-5 and hydrotris(indazolyl)borate thallium complexes 6-9 that contain linear perfluoroalkyl chains varying from two to six carbon atoms in the 3-position. In the solid state, the perfluorinated 1H-indazoles exhibit supramolecular structures that depend on the length of the perfluoroalkyl chain. A catemer of order 3 is observed for the CF 2CF3 derivative 2 (chiral space group P32), catemers of order 2 are observed for the C3F7 and C 4F9 derivatives 3 (chiral space group P212 121, one type of helix in the unit cell) and 4 (space group P21/n, two types of helices in the unit cell), respectively, and stacks of dimers are observed for the indazole with the longer C 6F13 chain 5 (space group P21/c). The perfluorinated hydrotris(indazolyl)borate thallium complexes 6-9 [TlFn-Tp 4Bo,3Rf] have been obtained by a new reaction based on the reaction of HBBr2 (generated in situ from BBr3 and Et3SiH) with the indazolates of 2-5 followed by cation exchange. The X-ray crystal structure of [TlF33-Tp4Bo,3C 3F7] 7 shows that, in addition to coordination to the three nitrogens, the thallium is buried in a nest of fluorines with seven short intramolecular Tl?F contacts with the pendant perfluoropropyl chains. The potential of these highly fluorinated molecules to act as ligands is highlighted. This journal is the Partner Organisations 2014.

Novel perfluoroalkyl vinyl ether compound, process for preparing copolymer by using the compound, and optical plastic materials comprising copolymer prepared by the process

Disclosed herein are a novel perfluoroalkyl vinyl ether compound, a process for preparing a copolymer by using the perfluoroalkyl vinyl ether compound, and an optical plastic material comprising a copolymer prepared by the process. More specifically, the perfluoroalkyl vinyl ether has a particular molecular structure; the process is performed by copolymerizing the perfluoroalkyl vinyl ether compound with a common fluorinated olefin in the presence of a perfluorinated radical initiator; and, the optical plastic material comprises a copolymer prepared by the process and optionally a dopant. The copolymerization of the perfluoroalkyl vinyl ether with a common fluorinated olefin can provide a copolymer having a high molecular weight. In addition, appropriate control of the composition of the monomers can provide a completely amorphous copolymer. Since the polymer prepared by the process exhibits excellent thermal properties and is substantially transparent in the UV and near IR regions, it can be usefully applied to various optical plastic materials. Furthermore, a preform for a GI type plastic optical fiber fabricated by using the copolymer and the dopant has a high Tg, thus being stable, and a parabolic refractive index profile due to the presence of the dopant.
