Abstract:
1. A lyotropic liquid crystal system comprising at least one 1,8-naphthoylene-1′,2′-benzimidazole sulfoderivative of the general structural formula: wherein: n is an integer in the range from 1 to 4; m is an integer in the range from 0 to 4; z is an integer in the range of 0 to 6, such that values of m, n, and z satisfy the equation m+z+n≦10; X and Y are individually selected from the group consisting of CH M is a counterion; and j is the number of said counterions in said lyotropic liquid crystal system, or selected from the group consisting of structures I–VIII: where m is an integer in the range of 0 to 3, and z is an integer in the range of 0 to 6; where m is an integer in the range of 0 to 4, and z is an integer in the range of 0 to 5; where m is an integer in the range of 0 to 2, and z is an integer in the range of 0 to 6; where m is an integer in the range of 0 to 4, and z is an integer in the range of 0 to 4; where m is an integer in the range of 0 to 3, and z is an integer in the range of 0 to 5; where m is an integer in the range of 0 to 3, and z is an integer in the range of 0 to 4; where m is an integer in the range of 0 to 2, and z is an integer in the range of 0 to 5; where m is an integer in the range of 0 to 2, and z is an integer in the range of 0 to 4; and X and Y are individually selected from the group consisting of CH
