실험 절차

A mixture of 3.5 g of anthracene-2,3-dialdehyde (E. Mallonli et al., Synthesis 1980, page 689), 1.8 g of succinodinitrile, 3 g of K2CO3 and 250 ml of dimethyl sulfoxide is heated with stirring at 60°-70° C. for 30 minutes. It is then cooled to 15° C. and 50 ml of water are added. The precipitate which has been deposited is filtered off and is sublimed at 300° C. Yield 485 mg (12%), λmax : 772 nm.
