The remarkable advances in molecular logic reported in the last decade demonstrate the potential of luminescent molecules for logical operations, a paradigm‐changing concerning silicon‐based electronics. Trivalent lanthanide (Ln3+) ions, with their characteristic narrow line emissions, long‐lived excited states, and photostability under illumination, may improve the state‐of‐the‐art molecular logical devices. Here, the use of monolithic silicon‐based structures incorporating Ln3+ complexes for performing logical functions is reported. Elementary logic gates (AND, INH, and DEMUX), sequential logic (KEYPAD LOCK), and arithmetic operations (HALF ADDER and HALF SUBTRACTOR) exhibiting a switching ratio >60% are demonstrated for the first time using nonwet conditions. Additionally, this is the first report showing sequential logic and arithmetic operations combining molecular Ln3+ complexes and physical inputs. Contrary to chemical inputs, physical inputs may enable the future concatenation of distinct logical functions and reuse of the logical devices, a clear step forward toward input–output homogeneity that is precluding the integration of nowadays molecular logic devices.

镧系元素发光模拟分子逻辑并通过物理输入进行计算
过去十年中报道的分子逻辑学的显着进步证明了发光分子在逻辑运算中的潜力，这是基于硅的电子学的范式变化。三价镧系（Ln 3+）离子具有特征性的窄谱线发射，长寿命的激发态以及在光照下的光稳定性，可能会改善最新的分子逻辑器件。在这里，使用结合了Ln 3+的单片硅基结构报告了用于执行逻辑功能的复合体。首次在非湿润条件下展示了开关比> 60％的基本逻辑门（AND，INH和DEMUX），顺序逻辑（键盘锁定）和算术运算（HALF ADDER和HALF SUBTRACTOR）。此外，这是第一份报告，显示了结合分子Ln 3+配合物和物理输入的顺序逻辑和算术运算。与化学输入相反，物理输入可能会在将来实现不同逻辑功能的串联和逻辑设备的重用，这是朝着输入-输出同质性迈出的明确一步，这阻止了当今分子逻辑设备的集成。
