Crystal structure of an ordered [WOF5]− salt: (1,10-phen-H)[WOF5] (1,10-phen = 1,10-phenanthroline)
Acta Crystallographica Section E: Crystallographic Communications, 2020 Crystals of 1,10-phenanthrolinium pentafluoridooxidotungstate(VI), (1,10-phen-H)[WOF5] (1,10-phen = 1,10-phenanthroline, C12H8N2), were obtained upon hydrolysis of WF6(1,10-phen) in CH3CN at 193 K.

A Close Look at the Local Structure of Functional Polymers: The Example of Poly(Vinylidene Fluoride)
Advanced Functional Materials, EarlyView.To accurately develop structure‐property relationships in functional macromolecules, it is increasingly important to consider the local chain arrangement in addition to long‐range order. It is demonstrated in the case of poly(vinylidene fluoride) that solid‐state nuclear magnetic resonance (NMR) spectroscopy can provide detailed insights into the local

Fluorine-programmed nanozipping to tailored nanographenes on rutile TiO2 surfaces
Science, 2019 Nanographenes on oxides The growth of nanographene islands and ribbons on metal surfaces can be accomplished on single-crystal metal surfaces through carbon-carbon coupling reactions, but the surfaces of oxides do not assist these reactions. Kolmer et al.

Fluorine patterning of graphene: Effects of fluorine content and temperature [PDF]
arXiv, 2020 In this paper we present a successful approach for the generation of partially fluorinated graphene structures. A computationally simple model optimized on a large DFT dataset quickly and precisely predicts experimentally observed structures. From the analysis of the structural diversity of fluorinated graphene in a wide range of synthesis temperatures,

Absence of stable atomic structure in fluorinated graphene [PDF]
, 2016 Based on the results of first-principles calculations we demonstrate that significant distortion of graphene sheets caused by adsorption of fluorine atoms leads to the formation of metastable patterns for which the next step of fluorination is considerably less energetically favorable.
