Control of crystal structures of fluorescent two-component supramolecular systems by varying substituents and their positions

Abstract

Although fluorescent, column-like supramolecular network structures were previously obtained by using 2-naphthalenecarboxylic acid and benzylamine or fluorobenzylamine, the use of chlorobenzylamine or bromobenzylamine results in column-like or 2D-layered network supramolecular structures, indicating that crystal structures can be controlled by altering the type and position of the substituent on the benzylamine component.
