The synthesis is rather convenient through one pot multistep reactions and no expensive reagents are involved. The products are formed via autoxidation-Michael addition mechanism and their structures were characterized by X-ray crystallographic analysis. Their crystal stuctures are stablilized by intermolecular hydrogen bonds and double-strand supramolecular stacking is observed.展开更多
