Synthesis of Organofluorine Compounds, been detected so far.. The best known is the plant metabolite CH.FCO.H (see Chapter 1); the other nine include the related compounds CH.FCOCH., 2-fluorocitric acid, F(CH.).CO.H (. = 9, 13, 15), and F(CH.).CH=CH(CH.).CO.H. The most intriguing by far is nucleo-cidin (1), an antibiotic fluoro-sugar derivative produced by the microorganisms ..

Fluorinated Liquid Crystals,rystalline phase. Through their anisotropy, liquid crystals are very sensitive to external changes such as electric field. Thus liquid crystals have been used as a practical means for monitoring, imaging, and other purposes.

Fluoroplastics,herability, low flammability, low surface energy, and outstanding resistance to most chemicals. The presence of only strong. C—F and C—C bonds in perfluoropolymers imparts a high degree of oxidative and hydrolytic stability which extends to a remarkable degree to less highly fluorinated analogs.
