photochromism

Example:The photoswitching properties of some photochromic molecules allow them to act as molecular switches.

Definition:A type of photochromism where the material exhibits a switch-like behavior in response to light irradiation, resulting in a distinct change in state or property.

Example:Phototropic polymorphism is observed in some materials that exhibit photochromism under specific light conditions.

Definition:A reversible transformation between different polymorphic forms of a material under light exposure, often involving a change in physical or chemical properties.
