Paper Abstract

The orientational order and rotational dynamics of 2-(3-(diphenyl-hexatrienyl) propanoy11-3-palmitoyl-L-a-phosphatidylcholine (DPH-PC) embedded in dioleoplphosphatidylethanolamine (DOPE) were studied by time-resolved fluorescence depolarization technique. Upon increasing the temperature, the wobbling diffusion constant D⊥ of DPH-PC was found to decrease at the lamellar (Lα) to inverted cylindrical (HII) phase transition (12°C). The calculated ratio of order parameter in the La phase to that in the HII phase was close to the theoretical value of 2.0 as predicted from the change in packing symmetry. The effects of butylated hydroxytoluene, cholesterol and phosphatidylchollne on this phase transition were also examined.
