| description | The invention discloses a liquid crystal composition with low viscoelastic ratio, large dielectric adjustability and low dielectric loss and a high-frequency component. The liquid crystal composition comprises one or more compounds as shown in a structural general formula I, wherein R is alkyl with the carbon atom number of 1-10, alkoxy, fluorinated alkyl, alkenyl with the carbon atom number of 2-10, alkenyloxy, fluorinated alkenyl, fluorinated alkenyloxy, naphthenic base with the carbon atom number of 3-8 or alkyl containing naphthenic base substitution; z1 and Z2 are single bonds,-C = C-,-CH = CH-,-CF = CF-or-CH2CH2; ring A and ring B are benzene rings or cyclohexane or cyclohexene, wherein hydrogen on the benzene rings can be substituted by fluorine, chlorine, methyl and ethyl; n is equal to 0 and 1. The liquid crystal composition disclosed by the invention not only can obtain relatively large dielectric tuning rate, extremely low dielectric loss, low rotary viscosity and relatively large elastic constant |
