摘要：
A NEMATIC LIQUID CRYSTAL COMPOSITION HAVING A VERY BROAD MESOPHASE COMPRISING A MIXTURE OF AT LEAST ONE COMPOUND OF THE FORMULA:
(4-R-PHENYL)-CH=N-(1,4-PHENYLENE)-R1
WHEREIN R AND R1 ARE RADICALS SELECTED FROM THE GROUP CONSISTING OF A SATURATED ALKOXY RADICAL AND AN ALKYL RADICAL, EACH HAVING FROM 1 TO 9 CARBON ATOMS AND ONLY ONE OF R AND R1 IS ALKYL; AT LEAST ONE COMPOUND OF THE FORMULA:
(4-R2-PHENYL)-CH=N-(1,4-PHENYLENE)-R3
WHEREIN R2 AND R3 ARE RADICALS SELECTED FROM GROUP CONSISTING OF A SATURATED ALKOXY RADICAL HAVING FROM 1 TO 9 CARBON ATOMS AND A SATURATED ACYLOXY RADICAL HAVING FROM 2 TO 5 CARBON ATOMS, AND ONLY ONE OF R2 AND R3 IS AN ALKOXY RADICAL; AND AT LEAST ONE COMPOUND OF THE FORMULA:
(4-(R4-(COO)X-)PHENYL)-OOC-(1,4-PHENYLENE)-(OOC)Y-R5
WHEREIN R4 AND R5 ARE SATURATED ALKOXY RADICALS OF FROM 1 TO 9 CARBON ATOMS, ONE OF X AND Y IS 0 AND THE OTHER IS 1.
(4-R-PHENYL)-CH=N-(1,4-PHENYLENE)-R1
WHEREIN R AND R1 ARE RADICALS SELECTED FROM THE GROUP CONSISTING OF A SATURATED ALKOXY RADICAL AND AN ALKYL RADICAL, EACH HAVING FROM 1 TO 9 CARBON ATOMS AND ONLY ONE OF R AND R1 IS ALKYL; AT LEAST ONE COMPOUND OF THE FORMULA:
(4-R2-PHENYL)-CH=N-(1,4-PHENYLENE)-R3
WHEREIN R2 AND R3 ARE RADICALS SELECTED FROM GROUP CONSISTING OF A SATURATED ALKOXY RADICAL HAVING FROM 1 TO 9 CARBON ATOMS AND A SATURATED ACYLOXY RADICAL HAVING FROM 2 TO 5 CARBON ATOMS, AND ONLY ONE OF R2 AND R3 IS AN ALKOXY RADICAL; AND AT LEAST ONE COMPOUND OF THE FORMULA:
(4-(R4-(COO)X-)PHENYL)-OOC-(1,4-PHENYLENE)-(OOC)Y-R5
WHEREIN R4 AND R5 ARE SATURATED ALKOXY RADICALS OF FROM 1 TO 9 CARBON ATOMS, ONE OF X AND Y IS 0 AND THE OTHER IS 1.
