This article describes an optically adjustable, dual complementary molecular TRANSFER and COMPLEMENT logic gate as well as an extremely rare design of excitation-modulated logic systems using a pyrene coupled bis(indolyl)methane derivative (1) in Brij-58 micelles, triggered by different chemical stimuli. We have looked into the optical response of the probe molecule towards variety of analytes, including OH, CN, Hg, EDTA ., at various excitation channels, in order to achieve this goal. By utilizing the probe's intriguingly distinct absorption spectra in response to the injection of OH, Hg, and CN individually or in succession, tunable molecular logic systems were created. In the current report, fundamental and combinational array structures for the logic circuits have been proposed. Furthermore, based on discernible fluorescence responses of the probe molecule towards unlike analytes at various emission wavelengths, a new type of excitation-modulated logic system has been developed.
本文描述了一种光学可调的双互补分子转移和互补逻辑门，以及一种极为罕见的激发调制逻辑系统设计，该系统在不同化学刺激触发下，使用芘偶联双（吲哚基）甲烷衍生物（1）在Brij - 58胶束中运行。为实现这一目标，我们研究了探针分子在各种激发通道下对包括OH、CN、Hg、EDTA等多种分析物的光学响应。通过利用探针在单独或连续注入OH、Hg和CN时有趣的独特吸收光谱，构建了可调谐分子逻辑系统。在本报告中，提出了逻辑电路的基本和组合阵列结构。此外，基于探针分子在不同发射波长下对不同分析物可辨别的荧光响应，开发了一种新型激发调制逻辑系统。
