The invention concerns a method for treating a fluid. According to the invention, the fluid is contacted with a substrate at the surface of which there is a network of organic molecules, hereafter referred to as 'network molecules'. There is a central core and at least one lateral arm, the molecules being adsorbed at the surface of the substrate. The invention also concerns a two-dimensional molecular sieve formed by the substrate at the surface of which a network of network molecules is adsorbed. The invention further concerns a module for treating a fluid including a circulating device for the fluid to be treated, the device containing one or more two-dimensional molecule sieves.

Method for treating a fluid using a self-organized network adsorbed on a surface

A transparent, organic polymer substrate organized for optical frequency conversion is prepared by subjecting a material of a transparent, organic polymer which incorporates therein transparent, active organic molecules which have a second order, microscopic, optical nonlinearity to the simultaneous action of a first laser beam at fundamental frequency .omega. and a second laser beam of second harmonic frequency 2 .omega. for a time adequate to induce a second order, macroscopic nonlinearity in the transparent active organic molecules in the structure.
