Separation of C₆₀ Indene

Buckyprep-D offers improved separation for C₆₀ indene, a derivatized fullerenes, that has received much attention as the n-type semiconductor material of organic thin-film solar cell.

Comparison with Conventional Buckprep Columns

Buckyprep-D retains derivatized fullerenes longer than C₆₀. Therefore it is more suitable for preparative separation of derivatized fullerenes than conventional Buckyprep column.
