Procedure

To a 10 oz. nitrogen purged bottle, hexane (20 mL), styrene (1 gr, 30% in hexane), butadiene (5 gr, 20% in hexane), oligomeric oxolanyl propane (OOPs) (0.03 mL, 1.6M solution) and butyl lithium (0.1 mL, 1.54M) would be added. The bottle would be placed into 80° C. water bath for 10 minutes. After cooling to 23° C., a charge of cinnamyl-1-methylpyrene ether (10 mL, 0.14M in cyclohexane) would be added into the bottle. After continual cooling for 5 minutes, a charge of DVB (0.5 mL) would be added to the mixture. The reaction would proceed for 1 hour, and then would be terminated by adding isopropanol 0.1 mL).
