The invention provides a kind of liquid-crystal composition and manufacture method, film, Polarizer and liquid crystal indicator.The present invention is a kind of manufacture method of liquid-crystal composition, it by making the carboxylic acid reaction shown in the carboxylic acid shown in the compound shown in formula (III) and formula (IV) and formula (V), and obtains the liquid crystalline cpd shown in formula (I) and the liquid crystalline cpd shown in formula (II) simultaneously.According to the present invention, can provide a kind of and use different carboxylic acids of more than two kinds as the one of raw material, and manufacture the method for the high liquid-crystal composition of crystallization rejection ability, solvability and liquid crystal liquid crystal property by single step.Formula (I) Pn 1 -Spn 1 -Tn 1 -An 1 -B-An 2 -Tn 1 -Spn 1 -Pn 1 ; Formula (II) Pn 1 -Spn 1 -Tn 1 -An 1 -B-An 3 -Tn 2 -X; Formula (III) HYn 1 -B-Yn 2 h; Formula (IV) Pn 1 -Spn 1 -Tn 1 -COOH; Formula (V) X-Tn 2 -COOH. |
