ХИРАЛЬНЫЙ БИС(КАМФОРОЛИДЕН)ЭТИЛЕНДИАМИН КАК ИНДУКТОР СПИРАЛЬНОЙ МЕЗОФАЗЫ В СМЕСИ АЛКОКСИЦИАНОБИФЕНИЛОВ
Аннотация
Исследованы мезоморфные, оптические и диэлектрические свойства нематиче-ской смеси 4-пентилокси и 4-гептилокси-4'-цианобифенилов допированной оптически ак-тивным бис(камфоролиден)этилендиамином. Методом поляризационной микроскопии измерены температуры просветления смесей. Проведена оценка степени дестабилизации мезофазы при введении допанта. Измерен шаг спирали индуцированной хиральной нема-тики в смесях. Изучено влияние хирального допанта на анизотропные характеристики мезофазы.
