Intramolecular Charge Transfer aromatic amines and their application towards molecular logic gate

The emission response of 1-aminopyrene and 2-aminoanthracene was found to be switched ON or OFF by interrupting the Intramolecular Charge Transfer processes of these integrated systems using two binary ionic inputs like H+ or/and OH−. These fluorescence responses in the presence of added H+ or/and OH− could be correlated with Half-subtractor logic operation, revealing the possibility of using simple molecules for demonstrating complex logic operations.
