  • Method for treating a fluid using a self-organized network adsorbed on a surface
    Patent number: 8377306
    Abstract: 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.

  • Polymers from certain conjugated organic compounds
    Patent number: 6051669
    Abstract: The invention relates to conjugated compounds of general formula (I) ##STR1## wherein X.sub.1 and X.sub.2 are, independently of one another, electron-withdrawing or electron-donating systems, and to a process for the preparation of these compounds.The invention also relates to any material which includes the compounds of general formula I and to the use of said compounds or of any material which includes them in electronic, optoelectronic, nonlinear optical and electrooptical devices.
