General description

Cholesteryl oleyl carbonate(COC) is a carbonate ester of cholesterol and oleyl alcohol with carbonic acid that is used as a liquid crystal(LC) molecule. It has is a crystalline material with a helical structure.

Application

COC can be incorporated in the polyethylene glycol(PEG)-polyurethane(PU) matrix that exhibits lower thrombogenicity and an improved haemocompatibility which can used as a biomaterial in biomedical applications. It may also be self-assembled with cadmium selenide(CdSe) quantum dots(QDs) for the fabrication of novel multifunctional switchable devices.
