Kinetics of light-induced mesophase transitions in azo-benzene amphiphiles containing lyotropic liquid crystals.

ABSTRACT: This study focuses on the kinetics of light-induced mesophase transitions in lyotropic liquid crystals containing a mixture of phospho-lipids and azo-benzene amphiphiles. Lipid membranes organize in a wide range of morphologies, directly influencing their functionality and the efficiency of associated components such as proteins. Transitions between mesophases occur naturally during membrane fusion and can also be triggered by multiple factors, such as pH, salinity, temperature and light. Employing light to isomerize artificial photoswitchable lipids in mixed model membranes containing 1,2-dipalmitoyl-phos-pha-tidylcholine or 1,2-didecanoyl-phosphatidylcholine revealed light-induced structural changes including mesophase transitions from a lamellar to a cubic Pn3m phase.
