基于分子性质的变化的存储器操作是重要的，因为它们可能导致器件小型化到分子尺度或超过二进制水平的日益复杂的信息处理协议。分子存储器还引入了与信息存储安全相关的可能性，其中化学信息（或试剂）可以用作加密密钥，在这种情况下，是酸性/碱性试剂。具有易失性和非易失性功能的化学存储器需要在至少两种化学上不同的稳定或准稳定状态之间的可逆转换。在这里，我们已经开发了苯酚荧光团的苯酚-酚氧平衡作为数据存储元件，它可以用于使用化学试剂写入或调制数据。该系统的特性允许以非易失性或易失性模式存储和擦除数据。我们还证明了非二进制开关的状态可能通过制备含有分子存储元件的复合材料。
Memory operations based on variation of a molecule's properties are important because they may lead to device miniaturization to the molecular scale or increasingly complex information processing protocols beyond the binary level. Molecular memory also introduces possibilities related to information-storage security where chemical information (or reagents) might be used as an encryption key, in this case, acidic/basic reagents. Chemical memory that possesses both volatile and non-volatile functionality requires reversible conversion between at least two chemically different stable or quasi-stable states. Here we have developed the phenol-phenoxide equilibrium of phenol fluorophores as a data storage element, which can be used to write or modulate data using chemical reagents. The properties of this system allow data to be stored and erased either in non-volatile or volatile modes. We also demonstrate non-binary switching of states made possible by preparation of a composite containing the molecular memory elements.
