Abstract The interest in the oxo-enol tautomerism of 1,3-dioxo compounds is justified by their usefulness in many synthetic fields. A series of new 1,3-bis(1-adamantyl)propan-1,3-diones with a variably substituted phenyl ring at the \{C2\} position was prepared either by the reaction of an appropriate Grignard reagent with adamatane-1-carbonyl chloride or by \{SEAr\} on the unsubstituted 1,3-bis(1-adamantyl)-2-phenylpropan-1,3-dione. In addition to the single crystal X-ray diffraction analysis of three of the prepared compounds, the experimental 1H and 13C NMR, İR\} and Raman spectroscopic data were assigned and compared to those obtained by \{DFT\} computations. In the solid state, the syn-dioxo forms were exclusively observed, which are shown to also predominate in \{CHCl3\} solutions. The analysis of the Hirshfeld surface revealed that H⋯H and O⋯H contacts dominate the intermolecular interactions in the solid state, whereas π⋯π stacking plays a marginal role.

Abstract Heparin-modified chitosan (H-chitosan) membrane was utilized to enhance biocompatibility of sodium selective membrane electrode based on the highly thrombogenic polyvinyl chloride (PVC). Sodium ion sensing film was prepared using PVC, sodium ionophore-X, potassium tetrakis(chlorophenyl)-borate, and o-nitrophenyloctylether. The PVC-based sensing film was sandwiched to chitosan or H-chitosan to prevent platelet adhesion on the surface of PVC. Potentiometric response characteristics of PVC-chitosan and PVC-H-chitosan membrane electrodes were found to be comparable to that of a control \{PVC\} based sodium-selective electrode. This indicates that chitosan and H-chitosan layers do not alter the response behaviour of the PVC-based sensing film. Biocompatibility of H-chitosan was confirmed by in vitro platelet adhesion study. The platelet adhesion investigations indicated that H-chitosan film is less thrombogenic compared to PVC, which could result in enhancement of biocompatibility of sodium selective membrane electrodes based on PVC, while maintaining the overall electrochemical performance of the PVC-based sensing film.
