Abstract

Halochromism has a plethora of uses in the textile industry, including wound treatments and protective apparel. Reactive dye’s fastness and a wide variety of hues, from bright to dull, make it ideal for coloring cotton and other regenerated cellulose fibers. It is also fundamentally paramount importance to determine the freshness of packaging foods. In this study, a halochromic probe, 4,4′-((1E,1′E,3E,3′E)-hydrazine-1,2-diylidenebis(prop-1-en-1-yl-3-ylidene))bis(N, N-dimethylaniline), HDBD, has been introduced utilizing a simple condensation reaction. Through the protonation and deprotonation process with the addition of acid and base in the non-aqueous medium, HDBD shows visual colorimetric as well as ratiometric UV–visible absorption spectral change. A colorimetric paper strip-based experiment has been demonstrated to detect trace amounts of acid and its reversibility with bases in non-aqueous solvents. Further, a dip-stick experiment was also carried out for the detection of acid-base vapor in a wide range of concentrations. Furthermore, the overlapping indicator method is explored to estimate acid dissociation constants in the non-aqueous medium. Moreover, we have constructed the INHIBIT (INH) and IMPLICATION (IMP) molecular logic gates exploring the reversibility of HDBD due to the cascade introduction of acid-base as chemical encoded inputs. Utilizing a reversible and reproducible detecting method, we have constructed a molecular-scale additional memory device that demonstrates binary logic “Writing-Reading-Erasing-Reading” and “Multi-write” functions. This finding provides a new way for designing acid-base indicators, which could estimate the acid dissociation constants of various acids in the non-aqueous environment which is fundamentally important in the field of acid-catalyzed organic synthesis.

基于叠氮的卤色分子变色龙
晕色法在纺织业中用途广泛,包括伤口处理和防护服。活性染料的牢度和从明亮到暗淡的各种色调使其成为棉花和其他再生纤维素纤维着色的理想选择。对于确定包装食品的新鲜度也至关重要。本研究利用简单的缩合反应引入了一种卤色探针--4,4′-((1E,1′E,3E,3′E)-肼-1,2-二亚基双(丙-1-烯-1-基-3-亚基))双(N, N-二甲基苯胺),即 HDBD。通过在非水介质中加入酸和碱的质子化和去质子化过程,HDBD 显示出直观的比色法和比率法紫外-可见吸收光谱变化。基于比色纸条的实验证明了在非水溶剂中检测微量酸及其与碱的可逆性。此外,还进行了浸渍棒实验,以检测各种浓度的酸碱蒸气。此外,我们还探索了重叠指示剂法,以估算非水介质中的酸解离常数。此外,我们还构建了抑制(INH)和暗示(IMP)分子逻辑门,探索了由于酸碱作为化学编码输入的级联引入而导致的 HDBD 的可逆性。利用可逆和可重现的检测方法,我们构建了一个分子级附加存储器件,它展示了二进制逻辑 "写入-读取-递增-读取 "和 "多写入 "功能。这一发现为设计酸碱指示器提供了一种新方法,它可以估算各种酸在非水环境中的酸解离常数,这在酸催化有机合成领域具有重要意义。

期刊介绍: Inorganica Chimica Acta is an established international forum for all aspects of advanced Inorganic Chemistry. Original papers of high scientific level and interest are published in the form of Articles and Reviews. Topics covered include: • chemistry of the main group elements and the d- and f-block metals, including the synthesis, characterization and reactivity of coordination, organometallic, biomimetic, supramolecular coordination compounds, including associated computational studies; • synthesis, physico-chemical properties, applications of molecule-based nano-scaled clusters and nanomaterials designed using the principles of coordination chemistry, as well as coordination polymers (CPs), metal-organic frameworks (MOFs), metal-organic polyhedra (MPOs); • reaction mechanisms and physico-chemical investigations computational studies of metalloenzymes and their models; • applications of inorganic compounds, metallodrugs and molecule-based materials. Papers composed primarily of structural reports will typically not be considered for publication.
