STRUCTURE AND LOCAL ORDERON THE RELATIONS BETWEEN THE SMECTIC PHASE TYPES B, E AND G

The miscibility relations between the liquid crystalline (1. c.) phases of Terephthylidene-bis-[4-n-butylaniline] (TBBA) and N-[4-n-Butyloxy-benzylidene]-4-ethyl-aniline (BBEA) with the 1. c. phases of other substances have been investigated and yielded the following variants of liquid crystalline polymorphism : TBBA : smectic 5, G, B, C, A, N ; BBEA : G, N. The newest stand of the system of the 1. c. phase types is discussed together with the relations to the 1. c. structure types
