Synthesis and characteristics of [60]fullerene polysiloxane stationary phase for capillary gas chromatography

A new type of fullerene-containing polysiloxane was synthesized by reacting [60]fullerene with azidopropyl polysiloxane directly. The polysiloxanes ha ve been used successfully as stationary phases for capillary gas chromatogr aphy. They displayed high column efficiency, wide operational temperature a nd high thermostability, and exhibited unique selectivity for many organic substances, such as alkanes, alcohols, ketones and aromatic compounds. The stationary phase was especially suitable for separation of high boiling-poi nt compounds like polycyclic aromatic hydrocarbons and phthalic esters, etc . It was also found that some alcoholic or aromatic positional isomers coul d be well separated on the column. The influence of the fullerene content o n the separation was also investigated.
