The disorder of perfluoroalkyl chains in crystals: Two case histories of interpretation and refinement

10.1016/j.jfluchem.2009.06.018

The research focuses on the disorder of perfluoroalkyl chains in crystals and their impact on the structural characteristics of materials, which is crucial for tuning the functional properties of materials with perfluoroalkyl residues. The study utilizes single crystal X-ray analyses to determine the structural details of these chains, with a particular emphasis on the challenges in modeling disorder in perfluoroalkyl residues in crystals. The experiments involve the self-assembly of N,N,N',N'-tetramethyl-1,4-phenylendiamine (TMPDA) with 1,4-diiodoperfluorobutane (PFDIB) or 1,6-diiodoperfluorohexane (PFDIH) to form co-crystals 3a and 3b, respectively. These co-crystals were analyzed using various techniques including 1H/19F NMR, IR spectroscopy, and thermal analysis. The X-ray crystal structure determination was performed using a Bruker SMART APEX diffractometer, and the structures were solved by SIR2002 and refined on F2 by SHELX-97. The research also discusses the refinement of perfluoroalkyl chains in single crystal structural studies, highlighting the importance of accurate modeling to obtain consistent and scientifically valuable data.
