Abstract
A method for the preparation and purification of compounds using a novel support, a tetrabenzo [a, c, g, i]-fluorene group (Tbf) comprising reacting a building block (A) containing a Tbf group (Tbf-A), with a second building block (B), to afford an intermediate compound (Tbg-A-B) followed by purifying the intermediate compound by adsorption on a carbon support, removing the intermediate compound from the support with a solvent and repeating the previous reactions using the required number of building blocks to synthesize the compounds followed by removal of the Tbf group to afford the desired compounds.
