A triethylenetetramine bearing anthracene and benzophenone as a fluorescent molecular logic gate with either-or switchable dual logic functions

Fluorescence behaviors of a triethylenetetramine bearing anthracene (AN) and benzophenone (BP) fragments at the respective ends, is studied in water, where effects of pH ([H.sup.+]) and metal cations on the emission properties is studied in detail. Results reveal that triethylenetetramine bearing AN and BP fragments acts as a fluorescent logic gate with either-or switchable dual logic functions, driven by [H.sup.+] and metal cations.
