Methodological synthesis of a new biocompatible bi-compartmental rhodamine based probe (L-3) provides a multi-inputs and multi-outputs molecular logic circuit based on simple chemosensing phenomena. Spectroscopic responses of Cu2+ and Hg2+ towards L-3 together with reversible binding of S-2 with L-3-Cu-2 and L-3-Hg-2 complexes help us to construct a thee-input molecular circuit on their control and sequential addition to a solution of L-3 in a mixed organo-aqueous medium. We have further successfully encoded binary digits out of these inputs and outputs which may convert a three-digit input string into a two-digit output string resulting a simple monomolecular logic circuit. Such a molecular 'Boolean' logic operation may improve the complexity of logic gate circuitry and computational speed and may be useful to employ in potential biocompatible molecular logic platforms.
