Popis: Technological applications of lipids may be possible through stabilization of various liquid-crystalline phases. One important approach to stabilized self-assembling materials utilizes polymerization of liquid-crystalline phases composed of reactive lipids. Polymerization of lipids has been utilized to modify the chemical and physical properties of lamellar assemblies (e.g., lipid monolayers, multilayers, and bilayer vesicles). In addition, polymerization of the lipid region of three-dimensional nonlamellar lipid-phase structures has recently been reported, including the reversed bicontinuous cubic (QII) phase, belonging to the space group Pn3m and the reversed hexagonal (HII) phase. Here we show that an easily prepared polymerizable monoacylglycerol combined in a 9/1 molar ratio with the corresponding polymerizable 1,2-diacylglycerol forms nonlamellar phases upon hydration at room temperature. Phase investigation using cross-polarized light, 2H NMR spectroscopy, and X-ray diffraction showed that the lipi...
