Bistable molecules are provided with at least one photosensitive functional group. As thus constituted, the bistable molecules are photopatternable, thereby allowing fabrication of micrometer-scale and nanometer-scale circuits in discrete areas without relying on a top conductor as a mask. The bistable molecules may comprise molecules that undergo redox reactions, such as rotaxanes and catenanes, or may comprise molecules that undergo an electric-field-induced band gap change that causes the molecules, or a portion thereof, to rotate, bend, twist, or otherwise change from a substantially fully conjugated state to a less conjugated state. The change in states in the latter case results in a change in electrical conductivity.
双稳态分子具有至少一个光敏功能基团。因此构成的双稳态分子是可光图案化的,从而可以在离散区域制备微米尺度和纳米尺度电路,而无需依赖顶部导体作为掩模。双稳态分子可能包括发生氧化还原反应的分子,例如轮烷和猫烷,或可能包括发生电场诱导的带隙变化的分子,导致分子或其中一部分旋转、弯曲、扭曲或以其他方式从基本完全共轭状态变为较少共轭状态。在后一种情况下,状态的变化导致电导率的变化。
