1 Perfluoroalkyl chain substituted perylene-3,4:9,10-tetracarboxylic diimide compounds and preparation thereof.

2 The invention discloses catalysts for synthesizing perfluoroalkyl iodide, a method for preparing the catalysts and a method for preparing the perfluoroalkyl iodide by applying the compounds.

3 The categories and properties of the perfluoroalkyl monomers were introduced in detail. They could be used as retanning agent, finishing agent, fatliquor, water-and stain-proofing agent etc.

4 Some coumarin compounds in the introduction of perfluoroalkyl specific location, you can make it show the unique physical and biological characteristics.

5 Studies in animals suggest perfluoroalkyl acid can affect the liver, which could result in changes in cholesterol levels.

6 Bernard Weiss of the University of Rochester in New York, an expert on toxins who was not involved in the research, said perfluoroalkyl acids are a known neurotoxin.

7 Comparisons between calculated and experimental spectra of the three perfluoroalkyl iodides were made and the result showed that theoretical calculation was in good agreement with experimental values.

8 The present invention provides a simple and efficient method for producing a nucleic acid base having a perfluoroalkyl group.

9 In refluxing acetonitrile, water could also undergo the similar addition with alkenyl perfluoroalkyl sulfones.
