Phospholipid polymers side chain

Ishihara K, Hanyuda H, and Nakabayashi N. Synthesis of phospholipids polymers having a urethane bond in the side chain as coating material on segmented polyurethane and their platelet adhesion resistant properties. Biomaterials, 1995, 16(11), 873-879. 

It turned out to be true that proteinoids, without any lipids, also form bimolecular membranes.Despite the fact that black proteinoid membranes are not as long-lived in the ultrathin state as phospholipid membranes, they last long enough to be examined. Those rich in hydrocarbon-rich amino acid side chains mostly display properties characteristic for BLMs. The same polymers are among those that most readily combine with lecithin. 

The materials (42)-(47) illustrate the photochromic behaviour exhibited by relatively simple molecules. However, photochroism is also known for polymeric materials and often involves cis-trans isomerization of an azobenzene unit incorporated into the polymer. For example, photochromic behaviour has been demonstrated when the azobenzene core is incorporated as either a main-chain polymer (48) [76] or as a side-chain in a phospholipid polymer (49) [77].
