実験手順

To a mixture of 1.0 gram of pentacene-5,7,12,14-tetrone in 100 mL of cyclohexanol was added 7.3 grams of aluminum tri(sec-butoxide). The reaction mixture was heated to 145° C. for 66 hours. The reaction mixture was cooled to room temperature and placed in a centrifuge. A dark solid was separated and washed 3 times with cyclohexanol followed by centrifugation. The residue was washed with acetone, isolated on a filter flask, and air dried to give pentacene
