moleculelor

Moleculelor is a fictional term used in theoretical discussions and science fiction to describe a hypothetical class of molecules with tunable, bistable electronic states. In this concept, moleculelors consist of a rigid, conjugated core that provides a stable electronic framework, plus peripheral substituents that can be varied to modulate properties. The central idea is that the molecule can exist in at least two distinct electronic or conformational states, which can be interconverted by external stimuli such as light, electric fields, or chemical redox processes. Each state exhibits different optical or electrical characteristics, enabling potential applications in information storage, sensing, or smart materials.

Design considerations emphasize synthetic accessibility, thermal and chemical stability, and the energy barrier between states. A successful moleculelor would balance extensive π-conjugation for addressable states with sufficient rigidity to maintain discrete configurations and prevent rapid, uncontrolled switching. It is important to note that there are no widely cited, experimentally verified examples of moleculelors in peer-reviewed chemistry literature; the concept remains largely within thought experiments and speculative literature used to illustrate principles of molecular electronics and switchable materials.

In speculative scenarios, researchers might imagine assembling moleculelors through modular coupling of planar aromatic cores with orthogonal linkers, potentially employing templating strategies or on-surface synthesis to enforce the desired conformations. Potential applications discussed include high-density molecular memory, responsive coatings, and nanoscale sensors, though practical realization would confront challenges in synthesis, reproducibility, and integration with larger devices.
