Purification of semiconductors with metal scavengers

Liquid crystalline semiconductors are particularly difficult to purify by standard purification methods because of their high tendency to form aggregates in solution. Crystallization methods cannot be used either because compounds are liquid crystalline at room temperature. Therefore, metal scavengers bound on the surface of silica gel particles have been used. They allow substantial purification of metal and ionic contaminants.
