Abstract:
Molecular photoswitches offer unparalleled spatiotemporal control over material properties, yet conventional binary systems are largely restricted to "on/off" logic. To meet the needs of higher-density data architectures and complex logic operations, we describe the design and synthesis of a novel multistate photoswitch by integrating a biomimetically operating phyllantidine framework with a dimethylaminoazobenzene moiety. This hybrid system transcends the binary paradigm by leveraging time-dependent controllability between the two photoswitching systems.

Reversible inhibitors like edrophonium bind to a specific part of the enzyme called the anionic catalytic site. They form noncovalent bonds, which means they are not strongly attached to the enzyme. This creates a temporary and less stable enzyme–inhibitor complex, leading to...
