Application 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.

Column size: 4.6mmI.D.×250mm; Mobile phase: toluene; Flow rate: 1.0 ml/min.; Detection: UV 325 nm; Temperature: 30 C; Sample: C60[Indene]2 (1.0mg/ml)

Comparison with Conventional Buckyprep Column

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

Adjustment of Retention by Mobile Phase
Comparison of Each Solvent
Adding hexane or heptane to toluene increases retention on Buckyprep-D, while adding methanol or acetonitrile decreases retention. The effect of solvents on retention is the opposite of the conventional Buckyprep column.

Table. Comparison of percentage of retention ratio of each solvent on Buckyprep-D

Y-axis: Percentage of capacity factor k' when it is 100% toluene
X-axis: 10% of each solvent added into toluene

Adding Methanol Decreases Retention
Retention may decrease when a polar solvent is added on Buckyprep-D. For example, by increasing the methanol concentration to 1%, the retention dramatically decreases.

Solution for Too Strong Retention on Buckyprep-D
If the retention of derivatized fullerens on Buckyprep-D is too strong, shorten column length or add additives in toluene to decrease retention.

Attention: 
Use HPLC Grade solvent or solvents after filtration or distillation. Except for alkali aqueous and strong acidic solutions, other solvents can be used (water-free pyridine and others). Depending on solvents, pay attention to high pressure caused by high solvent viscosity.

Note:
Baseline of Bukyprep-D is less stable relative to other fullerene columns. To stabilize baseline, let acetonitrile run through for 10 minutes before analysis.
