Abstract

Ujawniono m.in. sposób otrzymywania mieszaniny antyferroelektrycznej charakteryzujący się z tym, ze miesza się ze sobą co najmniej jeden związek racemiczny (będący równomolową mieszaniną enancjomerów R i S) i/lub achiralny, wybrany ze zbioru związków o wzorze ogólnym 1, w którym podstawniki lateralne X1, X2, X3, X4, X5, X6, X7 i X8 znajdujące się w pierścieniach benzenowych oznaczają niezależnie atom wodoru i fluoru; grupa mostkowa Z oznacza niezależnie wiązanie pojedyncze lub grupę COO, CH2CH2, CH2O, OCH2, podstawnik Y oznacza grupę CH3, C2H5, CHF, CHF2, CF3; indeksy n, m, r i t oznaczają niezależnie liczby całkowite od 1 do 8; indeksy p i s oznaczają niezależnie liczby 0 i 1, co najmniej jeden związek chiralny (enancjomer R lub S) wybrany ze zbioru związków o wzorze 1 i/lub jeden związek chiralny (enancjomer R lub S) wybrany ze zbioru związków o wzorze 2, w którym podstawniki lateralne X1-X8 i Y; grupa mostkowa Z oraz indeksy n, m, r, t, p i s mają znaczenie jak we wzorze 1 i/lub inny znany związek optycznie czynny o dużej sile skręcającej w proporcjach odpowiadających składowi eutektycznemu.
