Control of variable composition structures by fluorine substituent in supramolecular organic fluorophore composed of 2-naphthalenecarboxylic acid

Although three types of 2-naphthalenecarboxylic acid supramolecular organic fluorophores are obtained by using benzylamine, the resulting crystal structures using fluorobenzylamine instead of benzylamine is limited, and only two types of 2-naphthalenecarboxylic acid supramolecular organic fluorophores with different optical properties are formed. In addition, the formation of these supramolecular organic fluorophores can be controlled by changing the position of the fluorine substituent or the crystallization method.
