Biphasic Formation of 2D Nanomembranes by Photopolymerization of Diacetylene Lipids as Revealed by Infrared Difference Spectroscopy

Two-dimensional nanomembranes are promising materials for filtration or separation by providing the basis for controlled and rapid transport between two compartments. The polymerization by UV light of diacetylene-containing lipids at an interface produces free-standing 2D nanomembranes. Here, we analyzed in situ the nanomembrane formation of 1,2-bis(10,12-tricosadiynoyl)-sn-glycero-3-phosphocholine (DiynePC) and...
