Immobilization of functionalized lipids in a random poly(methacrylate) copolymer monolayer

1995

It is shown that a monolayer of random poly(methacrylate) copolymer with a hydrophobic and a hydrophilic substituent exhibits a transition from the fluid to amorphous state. Above this transition any amphiphilic molecules mixed with the monolayer are immobile. Furthermore, such functionalized lipids are immobilized in the monolayer during the Langmuir-Blodgett transfer. The hydrophilic head-groups of the biotin-lipids remain on the formerly water-adjacent side of the monolayer, even if this side is exposed to air

Preparation of Polymer-Supported Polyazamacrocycles. The Role of the Polymeric Matrix in the Preparation of Polymer-Supported Polyazamacrocycles

2000

Different approaches have been studied for the preparation of resins containing different polyazamacrocycles. Preparation of monolithic resins by polymerization of vinylic derivatives of the corresponding macrocycles is shown to be a more versatile strategy for this purpose. The use of energy-dispersive analysis by X-ray has revealed to be a very useful tool for the rapid evaluation of the interaction of those materials with both anions and cations and has allowed the corresponding selectivity trends to be obtained in a fast and simple way. Important effects of the polymeric matrix are observed in some cases.
