| Description |
Organic molecules with the possibility of logic operations are highly useful building blocks for the development of molecule-based ‘‘intelligent’’ devices for information processing applications. We have designed herein a very simple bio-friendly chemosensor (LC) equipped with a rhodamine fluorophore moiety. This probe showed a chromo-fluorescence response profile for Al3+ but a colorimetric response for Cu2+ metal. The absorption responses of LC caused by these metal ions along with the ‘‘OFF–ON–
OFF’’ fluorescence behavior of an LC–Al3+ complex towards EDTA were employed for the development of a three-input and one output combinatorial molecular system. Interactions of the mentioned metal ions with LC in controlled sequential experiments gave fluorescence responses, enabling us to fabricate a ‘key-pad-logic’ function. So, a single molecular system performing such multiple ‘Boolean’ operations not only simplifies the complexity of a chemical driven ‘Intelligence’ device but also enriches the
security of such a device against information invasion due to the sequence controlled sensor–analyte interactions and may find potential applications in biocompatible molecular logic platforms
