Detailed Nuclear Magnetic Resonance (NMR) spectroscopy investigations on a novel naphthalene-substituted 1,2,3-triazole-based fluorescence sensor provided evidence for the "turn-on" detection of anions. The one-step, facile synthesis of the sensors was implemented using the "Click chemistry" approach in good yield. When investigated for selectivity and sensitivity against a series of anions (F − , Cl − , Br − , I − , H 2 PO 4 − , ClO 4 − , OAc − , and BF 4 − ), the sensor displayed the strongest fluorometric response for the fluoride anion. NMR and fluorescence spectroscopic studies validate a 1:1 binding stoichiometry between the sensor and the fluoride anion. Single crystal X-ray diffraction evidence revealed the structure of the sensor in the solid state.

“…We have concentrated on molecular logic gate arrays and not the simpler gates themselves, about which much has been written. [149][150][151][152][153] Molecular gate arrays with sequential logic, for example, keypad locks, [154][155][156][157][158][159][160][161][162][163][164][165] flip-flops, [166] and flipflap-flops [143] have not been featured in this review either, as this topic has been addressed recently. [167] The field of molecular logic and computation appears to be in good health, especially regarding the understanding of chemical situations in terms of computer science principles.…”

Chemists are now able to emulate the ideas and instruments of mathematics and computer science with molecules. The integration of molecular logic gates into small arrays has been a growth area during the last few years. The design principles underlying a collection of these cases are examined. Some of these computing molecules are applicable in medical- and biotechnologies. Cases of blood diagnostics, 'lab-on-a-molecule' systems, and molecular computational identification of small objects are included.

“…The latter are macroscopic analytical devices that, similar to the way the olfactory system operates, can interact non‐specifically with a wide range of analytes and discriminate among them by creating a wide range of unique identification patterns . Hence, the main difference between 8 and the molecular keypad locks discussed before is that instead of generating a single digital output (0 or 1) for each code entry, it associates each password with a unique emission “signature” that enables it to authorize multiple users.…”

User Authorization at the Molecular Scale

Electronic user authorization systems help us maintain our privacy in many aspects of everyday life. However, the increasing difficulty to secure access and/or information digitally has inspired chemists to devise alternative, molecular approaches, in which users are identified by chemical means. The potential advantages of using molecular user authentication systems over conventional electronic devices are their versatility and unusual operating principles, which complicate replicating and, consequently, breaking into molecular security devices. Their molecular scale is another unique property that enables hiding such systems and, consequently, applying steganography as an additional layer of protection. Although the area of molecular‐based user authorization is still in its infancy, the development of various molecular keypad locks and, more recently, a password‐protected molecular cryptographic machine, indicate the possibility of protecting information at the molecular scale.
