Diacetylenic sterols: new potentially photopolymerizable lipids
Abstract
Cholesterol analogues with a diacetylenic moiety in their side chains have been prepared from bisnorcholenic acid, using 1,4-bis(trimethylsilyl)buta-1,3-diyne as the synthon to introduce the polymerizable group. A preliminary study of their potential as polymerizable sterols has been carried out by exposing aqueous dispersions (with or without phospholipids) to UV light at 5 °C.
