Effect of phenyl group on the self assembly of N,N′-bis-(2-phenylglycinyl)pyromellitic diimide with aromatic hydrocarbons

The presence of the phenyl substituent in N,N'-bis-(2-phenylglycinyl)pyromellitic diimide (L2) facilitate the aromatic C-H center dot center dot center dot pi interactions of the guests such as anthracene and perylene and play the crucial role in directing the hydrogen bonding motif involving the carboxylic acid groups of L2.
