4. 3 of THF with 0.010 g of DIDE-resin (DIDE content, 0.028 mmol / g-Resin). Then 0.190 g of AS was dissolved in the previous THF solution. The THF solution thus prepared was poured onto a flat laboratory dish and the solvent allowed to evaporate. The print molecule was extracted by methanol till the print molecule could scarcely detected by UV analysis.
