"Rotaxanes" Meaning
Rotaxanes are a type of mechanically interlocked molecular architecture. In a rotaxane, a linear molecule (the axle) is threaded through a molecular ring (the wheel), and the two components are mechanically bonded together through covalent bonds.
Imagine a mechanical embodiment of a sliding door: the axle is like the door's rod, and the wheel is like the door. However, unlike a sliding door, the axle cannot be removed from the wheel in the case of a rotaxane.
Rotaxanes have unique properties due to their mechanical bonding:
1. Stability: The mechanical bonding between the wheel and the axle provides additional stability to the molecule.
2. ﾍSelective binding: The wheel-axle interaction can be selective, allowing the molecular system to bind specifically to certain targets.
3. Switching behavior: Rotaxanes can exhibit switching behavior by moving the wheel along the axle in response to external stimuli, such as changes in temperature, pH, or the presence of specific molecules.
Rotaxanes have various applications in fields like:
1. Supramolecular chemistry: Studying the interplay between the wheel and axle components provides insights into molecular recognition, binding selectivity, and energy transfer.
2. Molecular machines: Rotaxanes can be designed to perform tasks such as switching, oscillating, or pumping, which can lead to innovative self-assembly and nanoscale device applications.
3. Biomimetics: Rotaxane-based systems can be used to model biological processes, such as protein function, folding, and interactions.
4. Materials science: Rotaxanes can be utilized in the development of shape-memory materials, switchable metamaterials, and self-healing composites.
Overall, the interlocked architecture of rotaxanes enables sophisticated control and manipulation of molecular interactions, leading to a wide range of interesting properties and applications.

Rotaxane
A rotaxane is a type of molecular architecture in organic chemistry. It consists of a macrocycle ('ring') that encircles a dumbbell-shaped component (axis), which contains two terminal groups. The macrocycle is mechanically bound to the axis by two end groups (á stators) through a process called coordination bonding.<br><br>Rotaxanes can be viewed as a combination of a macrocycle and a dumbbell-shaped molecule linked together. The macroring encircles the axis in a specific orientation and is held together by weak chemical bonds (e.g. dipole-dipole forces, van der Waals forces), which can be too weak to separate the component, hence the term "mechanochemical" is not used for molecules that sustain such bonds between their constituent parts.<br><br>Rotaxanes can be considered as a type of molecule that consists of three parts described as a macrocycle and two ends in which two of its non-covalent closures of the dumbbell-shaped axis.

Rotenone
Rotenone is a naturally occurring chemical insecticide derived from the roots of certain plants, such as the Derris tree. It is a non-selective insecticide that works by inhibiting the energy-producing process in cells, killing insects and other organisms by suffocation. Rotenone is used to control insect pests, particularly in agriculture and in aquariums. It is also used in some fisheries to remove insects and other unwanted organisms from the water.
