Synthetic biological approaches, such as site-directed biosynthesis, have contributed to the expansion of the chemical space of natural products, making possible the biosynthesis of unnatural metabolites that otherwise would be difficult to access. Such methods may allow the incorporation of fluorine, an atom rarely found in nature, into complex secondary metabolites. Organofluorine compounds a...
Development of hydrophobic surfaces with a low friction coefficient is an impressive strategy for improving performance self-cleaning glasses and photovoltaic cells. To this end, diamond-like carbon (DLC) films have been fabricated by plasma-enhanced chemical vapor deposition (PECVD) varying the fluorine concentration film. As introduced to DLC film, some fluorocarbon compounds, including CF CF...
Strategic replacement of protons with fluorine atoms or functional groups fluorine-containing fragments has proven a powerful strategy to optimize the activity therapeutic compounds. For this reason, synthetic chemistry organofluorides been subject intense development and innovation for many years. By comparison, literature on biocatalysis still makes slim chapter. Herein we introduce S-adenosy...
We present experimental results on the bulk flexoelectric coefficients e and effective elastic coefficients K of non-symmetric bimesogenic liquid crystals when the number of terminal and lateral fluoro substituents is increased. These coefficients are of importance because the flexoelastic ratio e/K governs the magnitude of flexoelectro-optic switching in chiral nematic liquid crystals. The stu...
