  • Publication number: 20200165197
    Abstract: The present invention relates to asymmetric sulfonamide compounds comprising at least: one polycyclic group, Ar, formed of two to six rings, at least one of which is aromatic, a linear or branched, saturated or unsaturated aliphatic chain, said chain possibly being interrupted by one or more heteroatoms, said group Ar and said aliphatic chain being covalently bonded via a spacer represented by a sulfonamide unit —SO2—NH— or its anionic form —SO2—N?-; and, optionally a counter-cation of the anionic form of the sulfonamide unit, chosen among the alkali metals and the proton H+. These compounds are of particular interest as single-ion conducting polymer electrolyte.

  • Patent number: 8758508
    Abstract: The invention relates to a method for forming a thin film of molecular organic semiconductor material (OSCM), said film being intended to be integrated into a device for applications in electronics or optoelectronics, which includes the following steps: step (c) of supplying a defined quantity of the molecular OSCM in the form of a melt to the surface of a substrate so as to form a thin film; and a step (d) of cooling according to a defined temperature profile in order to solidify the thin film, characterized in that the temperature of the substrate surface is equal to or above the melting point of the molecular OSCM at the moment of implementing step (a) and in that the temperature profile of step (b) comprises: a first part corresponding to a sufficiently slow controlled cooling of the molecular OSCM down to a temperature close to the crystallization temperature of the molecular OSCM, so as to cause only a single seed to appear in the thin film in melt form; and a second part corresponding to controlled coo

  • Patent number: 7390439
    Abstract: The invention relates to the use of sulphonic, phosphonic and phosphoric acids functionalized with plasticizing groups as dopants for conductive polyaniline films and for conductive polyaniline-based composite materials. These acids correspond to the following formula (I): in which: R1 represents —SO2(OH) or —PO(OH)2 or —OPO(OH)2; the R2 groups, which are identical or different, represent a hydrocarbonaceous group, such as a 2-ethylhexyl, butoxyethyl or isopropylbenzyl group; R3 and R4 independently represent a direct bond or a hydrocarbonaceous group, such as a methylene group.
