      abstract     = {The functionality and efficiency of proteins within a
                      biological membrane are highly dependent on both the
                      membrane lipid composition and the physiochemical properties
                      of the solution. Lipid mesophases are directly influenced by
                      changes in temperature, pH, water content or due to
                      individual properties of single lipids such as
                      photoswitchability. In this work, we were able to induce
                      light- and temperature-driven mesophase transitions in a
                      model membrane system containing a mixture of
                      1,2-dipalmitoyl-phosphatidylcholine phospho­lipids and
                      azo­benzene amphiphiles. We observed reversible and
                      reproducible transitions between the lamellar and Pn3m cubic
                      phase after illuminating the sample for 5 min with light
                      of 365 and 455 nm wavelengths, respectively, to switch
                      between the cis and trans states of the azo­benzene N=N
                      double bond. These light-controlled mesophase transitions
                      were found for mixed complexes with up to $20\%$ content of
                      the photosensitive molecule and at temperatures below the
                      gel-to-liquid crystalline phase transition temperature of
                      33°C. Our results demonstrate the potential to design
                      bespoke model systems to study the response of membrane
                      lipids and proteins upon changes in mesophase without
                      altering the environment and thus provide a possible basis
                      for drug delivery systems.},
