Abstract
Recent research in molecular logic gates produced molecular equivalence of highly
complex digital designs. Advanced data processing at the molecular level requires a
considerable degree of integration (concatenation) between molecular logic gates. So
far, almost all the integration reported in the literature has been “virtual”, meaning
that the outputs at various channels are determined first and then an integrated set of
logic gates is proposed to be operating on inputs to produce those outputs.
Nevertheless, there is no doubt that at some point there has to be methods to
physically connect one molecular logic gate to the other one, for a rational design and
implementation. In this study, we synthesized a few derivatives of the well known
fluorophore “Bodipy” and then proposed two methodologies to concatenate
separately existing and functioning Bodipy-based chemical logic gates. In one
instance, we coupled a photochromicity-based AND gate to an ion-responsive
Bodipy-based AND gate, making use of the modulation of inner filter effect. In the
other example, we coupled two ion-responsive Bodipy-based AND gates through the
increased efficiency of energy transfer and “click” chemistry. We are certain that
these methodologies are highly promising and our studies are in progress to
demonstrate more complex examples of physical integration.
