Document Type and Number:
Japanese Patent JP4587644
Kind Code:
B2
Abstract:
Indenes and 1,7-dihydroindacenes have negative dielectric anisotropy (DELTAepsilon). Indenes and 1,7-dihydroindacenes with negative dielectric anisotropy (DELTAepsilon) are of formulae (I) and (II) respectively. T = CF2, CHF, CH2 or CO; A = 1,4-phenylene (optionally with CH replaced once or twice with N and optionally with 1-4 CH substituted by halogen, CN, CH3, CH2F, CF3, OCH3, OCH2F, OCHF2, or OCF3), 1,4-cyclohexylene, 1,4-cyclohexenylene or 1,4-cyclohexadienylene (optionally with CH2 replaced once or twice by O or S and once or more optionally substituted by halogen); R = H, 1-15C alkyl, alkoxy, alkenyl or alkynyl (each optionally substituted once by CF3 or halogen and/or with one or more CH2 replaced by O, S, CO, COO, OCO, or OCO-O with heteroatoms non-adjacent), CN, SCN, NCS, SF5, CF3, OCF3, OCHF2, or OCH2F; L = H or halogen; X = H, 1-15C alkyl, alkoxy, alkenyl or alkynyl (each optionally substituted once by CF3 or halogen and/or with one or more CH2 replaced by O, S, CO, COO, OCO, or OCO-O with heteroatoms non-adjacent), halogen, CN, SCN, or NCS; U, W, Y = H, 1-15C alkyl, alkoxy, alkenyl or alkynyl (each optionally substituted once by CF3 or halogen and/or with one or more CH2 replaced by O, S, CO, COO, OCO, or OCO-O with heteroatoms non-adjacent); Z = a bond, CF2O, OCF2, CH2CH2, CF2CF2, C(O)O, OC(O), CH2O, OCH2, CF=CH, CH=CF, CF=CF, CH=CH or Ctriple bondC; and m,n,p,q = 0, 1, 2, or 3. In (I), L = F when T = CH2 and p,q = 0.
