This study presents the development of a novel time-dependent logic behaviour system and a state-of-the-art inter-switchable ternary molecular logic system, comprising 3-input INHIBIT and 3-input TRANSFER logic gates driven by elementary chemical interactions. The absorption spectra of the probe molecule underwent versatile time-dependent changes upon the individual and simultaneous addition of two analytes, namely F and CN, leading to alterations in the logic behaviour observed at both the 295 nm (from AND to TRANSFER) and 400 nm bands (from OR to INHIBIT). Additionally, we explored the creation of wavelength-guided molecular logic systems that leverage reversible (F and HO) and irreversible (CN and HO) chemical interactions. By employing CN and HO as dual chemical inputs, we derived binary TRANSFER, 2-input PASS 0, and binary COMPLEMENT logic gates based on the opto-chemical responses at 295 nm, 400 nm, and 500 nm, respectively. Lastly, we introduced an innovative inter-switchable ternary molecular logic system, involving 3-input INHIBIT and 3-input TRANSFER logic gates, using F, CN, and HO as ternary chemical inputs, capitalizing on the probes' versatile and distinct absorption responses at varying wavelengths (400 and 295 nm, respectively).
本研究展示了一种新型的时间依赖逻辑行为系统和一种先进的可相互切换的三元分子逻辑系统的开发，该系统由基于基本化学相互作用驱动的3输入抑制和3输入转移逻辑门组成。当分别或同时添加两种分析物F和CN时，探针分子的吸收光谱经历了多种时间依赖变化，导致在295nm（从与门变为转移门）和400nm波段（从或门变为抑制门）观察到的逻辑行为发生改变。此外，我们探索了利用可逆（F和HO）和不可逆（CN和HO）化学相互作用创建波长引导的分子逻辑系统。通过将CN和HO用作双化学输入，我们分别基于295nm、400nm和500nm处的光化学响应，推导出了二元转移、2输入通0和二元互补逻辑门。最后，我们引入了一种创新的可相互切换的三元分子逻辑系统，该系统涉及3输入抑制和3输入转移逻辑门，使用F、CN和HO作为三元化学输入，利用探针在不同波长（分别为400nm和295nm）下的多功能且独特的吸收响应。
