    Abstract

    1,2-Bis(2-4-octadecadienoyl)-sn-glycero-3-phosphorylcholine (DODPC), which had a diene group in 2,4-position of 1- and 2-acyl chains, was used to detect phase transition from shift of absorption maximum (λmax) due to the change of interaction of diene groups. Selective polymerization of 1-acyl chains of DODPC with AIBN gave linear phospholipid polymers which had unreacted diene groups in 2-acyl chains. From the analysis of λmax of thus selectively-polymerized liposomes, the phase transition behavior was detected clearly. We also studied the phase transition behavior of liposomes of which either layer of bilayer was selectively polymerized.
