Abstract
Smectic phases are obtained by self-organization of proton accepters a nd donors which fulfil the two conditions: a suitable pK(s)-value of t he carboxylic acid and a molecular shape of the associate which is abl e to form mesophases. Following this concept associates with smectic B phases and al the first time the crystalline S-E modification were de signed. The existence of the phases was proven by calorimetric, micros copic and X-ray investigations.
