A method is provided for preparing an organic film on the surface of a solid support including the steps of (a) applying, to the surface, by transfer or by spraying, a solution containing at least one cleavable aryl salt; and (b) subjecting the solution to a UV or visible irradiation, such that irradiation radical entities are formed from the cleavable aryl salt and an organic film is grafted. Further provided is a kit of elements for the implementation of such a method.

Process for preparing an organic film at the surface of a solid support by transfer or by spraying

This invention relates to a method for preparing an organic film at the surface of a solid support, with a step of contacting said surface with a liquid solution including (i) at least one solvent, (ii) at least one adhesion primer, under non-electrochemical conditions, and allowing the formation of radical entities based on the adhesion primer. The liquid solution can also include (iii) at least one monomer different from the adhesion primer and radically polymerizable. This invention also relates to a non-electrically-conductive solid support on which an organic film according to said method is grafted, and a kit for preparing an essentially polymeric organic film at the surface of a solid support.

Water purification using cyclodextrins

The invention relates to substituted derivatives of per(3,6-anhydro)cyclodextrins, their preparation process and their use for the separation of ions. These derivatives comply with one of the formulas: ##STR1## in which the R.sup.1, which can be the same or different, represent H, a halogen, OH, OR.sub.2, OM, SH, SR.sup.2, OCOR.sup.2, NH.sub.2, NR.sup.2 R.sup.3, CONR.sup.2 R.sup.3, CONH.sub.2, CN, COOR.sup.2, COOH, OSO.sub.2 R.sup.2, N.sub.3 or R.sup.2, and n=5, 6 or 7, provided that all the R.sup.1 do not represent OH.
