Abstract

original image

An on/off relationship: A supramolecular binary “OR” logic gate that generates highly enhanced fluorescence emission as the output signal is demonstrated (see picture). The system comprises a mixture of organogelator and photochromic compound and is able to process dual inputs of UV irradiation and thermal heating.
