Abstract:
This article describes an optically adjustable, dual complementary ternary molecular TRANSFER and COMPLEMENT logic gate as well as an extremely rare design of excitation-modulated logic systems using a pyrene coupled bis(indolyl)methane derivative (1) in Brij-58 micelles, triggered by different chemical stimuli. We have looked into the optical response of the probe molecule towards variety of analytes, including OH-, CN-, Hg2+, EDTA etc., at various excitation channels, in order to achieve this goal. By utilizing the probe's intriguingly distinct absorption spectra in response to the injection of OH-, Hg2+, and CN- individually or in succession, tunable molecular ternary logic systems were created. In the current report, fundamental and combinational array structures for the ternary logic circuits have been proposed. Furthermore, based on discernible fluorescence responses of the probe molecule towards unlike analytes at various emission wavelengths, a new type of excitation-modulated logic system has been developed.
