Title (EN) LIQUID CRYSTAL POLYMERS
(FR) POLYMERES A CRISTAUX LIQUIDES
Abstract:
(EN) Compounds of formula (I) are provided which may be used in a variety of devices including liquid crystal devices, piezoelectric devices, pyroelectric devices and in optical recording media; in said formula n = at least 5; Rx, Ry, Rz are independently selected from formula (IA), wherein Y is selected from COO, OCO, O, S, CHOH, CHF, CH2; Q = (CH2)n wherein one or more non-adjacent methylenes may be replaced by O and n = 1 - 20; Z is selected from O, S, single covalent bond, COO, OCO; when Y is CH2 then n may also be 0; (IB) represents any mesogenic group; Rx, Ry, Rz are also independently selected from H, OH, OCOR1, COOH, CO2R1, (CH2)pOH, (CH2)pCO2H, -(CH2)pOR1 or -(CH2)pCO2R1 and p = 1 - 20, R1 = H or C1-16 alkyl; when R1 = C2-16 alkyl the terminal CH3 group may be replaced by Br or Cl; provided that at least one of Rx, Ry, Rz is selected from formula (IA).
(FR) L'invention concerne des composés représentés par la formule (I), qu'on peut utiliser dans une variété de dispositifs, y compris des dispositifs à cristaux liquides, des dispositifs piézo-électriques, des dispositifs pyroélectriques, ainsi que dans des supports d'enregistrement optique: dans cette formule, n = au moins 5; Rx, Ry, Rz sont sélectionnés indépendamment dans la formule (IA): dans laquelle Y est sélectionné parmi COO, OCO, O, S, CHOH, CHF, CH2; Q = (CH2)n où un ou plusieurs méthylènes non contigus peuvent être remplacés par O et n = 1-20; Z est sélectionné parmi O, S, une liaison covalente simple, COO, OCO; quand Y représente CH2, n peut également être 0; (IB) représente un groupe mésogène quelconque; Rx, Ry, Rz sont également sélectionnés indépendamment parmi H, OH, OCOR1, COOH, CO2R1, (CH2)pOH, (CH2)pCO2H, -(CH2)pOR1 ou -(CH2)pCO2R1 et p = 1-20, R1 = H ou alkyle C1-16; quand R1 = alkyle C2-16, le groupe terminal CH3 peut être remplacé par Br ou Cl; à condition qu'au moins l'un des symboles Rx, Ry, Rz soit sélectionné dans la formule (IA).
