Synthesis and characterization of side-chain cholesterol derivatives based on double bond

After steps of esterification, epoxidation and ring-opening, a series of novel monomers of 5-hydroxyl-6-methacryloyloxy-3-alkylate, CnCOOCh (n = 1, 2, 3, 4, 5) were synthesized. After that, the corresponding polymers (PnCOOCh, n = 1, 2, 3, 4, 5) were obtained by free radical polymerization. The molecular structure, composition and thermal behaviors of monomers and polymers were confirmed by 1H NMR, FTIR, single crystal diffractometer, GPC, DSC and TGA. The results indicate that although their molecular weights are not high, all the polymers have high glass transition (Tg) and degradation temperature. In addition, Tg gradually decreases with increasing of alkyl chain lengths, and the degradation temperature increases with the increase of carbon number.

MESOMORPHISM OF CHOLESTERYL HALOPROPIONATE.

Mesomprphisms of several cholesteryl monohalopropionates have been studied. The beta -monohalopropionates exhibited a cholesteric liquid crystal phase, but the alpha -monohalopropionates had no mesophase. These results were explained by the lateral dimensions of rigid lathlike cholesteryl compounds.
