【摘要】：在科學(xué)研究和工農(nóng)業(yè)生產(chǎn)、環(huán)境保護(hù)等很多領(lǐng)域,化學(xué)量的檢測與控制技術(shù)正在得到越來越廣泛的應(yīng)用,而化學(xué)傳感器是這個(gè)過程的首要環(huán)節(jié)。近幾十年化學(xué)傳感器的研究和發(fā)展表明,化學(xué)傳感器的應(yīng)用已深入人們現(xiàn)代生活的各個(gè)方面,環(huán)境保護(hù)和監(jiān)控,預(yù)防災(zāi)難和疾病的發(fā)生,仍然是當(dāng)前乃至今后相當(dāng)長時(shí)期化學(xué)傳感器應(yīng)用的主要領(lǐng)域。Salen型和Salamo型化合物是一種多功能的螯合配體,其金屬配合物在結(jié)構(gòu)化學(xué)、立體化學(xué)、磁學(xué)、立體異構(gòu)、配位化學(xué)、光譜學(xué)、分析化學(xué)、催化、光電顯示、攝影、農(nóng)業(yè)以及光致變色等領(lǐng)域都有重要的作用。在本文中通過一個(gè)基于萘環(huán)的長鏈Salamo型配體超分子結(jié)構(gòu)和性質(zhì)的研究,尤其超分子配體和配合物作為熒光化學(xué)傳感器的性質(zhì)進(jìn)行了深入研究,得到了兩個(gè)具有應(yīng)用前景的熒光化學(xué)傳感器。全文分為四個(gè)章節(jié)進(jìn)行討論:一、本章節(jié)主要介紹了研究背景。重點(diǎn)介紹了超分子領(lǐng)域的發(fā)展概況,包括Salen型和Salamo型化合物的研究近況,熒光化學(xué)傳感器的研究近況,傳感器主體識別客體的機(jī)理以及具有代表性的實(shí)例。另外對論文的選題的意義進(jìn)行了闡述。二、我們設(shè)計(jì)并合成了一個(gè)萘環(huán)基的雙邊四肟型配體,同時(shí)我們得到了配體與鋅(Ⅱ)、銅(Ⅱ)和鈷(Ⅱ)的醋酸鹽反應(yīng)得到的三核金屬配合物,并通過單晶衍射儀測得了相應(yīng)的晶體結(jié)構(gòu)。然后分別用核磁氫譜儀、熔點(diǎn)測定儀、紫外-可見光譜儀、熒光光譜儀等表征手段,測定了配體和三種金屬配合物的結(jié)構(gòu)和性質(zhì)。我們對金屬配合物結(jié)構(gòu)進(jìn)行了分析討論,研究了分子內(nèi)和分子間的作用力,以及分子間一維和二維的構(gòu)型;通過紫外滴定實(shí)驗(yàn)確定了配體和金屬離子的配比。三、研究了配體可以作為繼熒光傳感器識別含水有機(jī)體系中的鋅(Ⅱ)離子和苦味酸根離子。我們研究了繼電傳感器H4L的穩(wěn)定性和靈敏性,發(fā)現(xiàn)其符合傳感器的要求。通過以上結(jié)論,我們認(rèn)為繼電傳感器有三個(gè)優(yōu)點(diǎn):pH適應(yīng)范圍大;穩(wěn)定性好;以及響應(yīng)靈敏,可以用于實(shí)際應(yīng)用中用于檢測自然水中的Pic-離子。四、我們探索了配體和鋅(Ⅱ)配合物作為pH熒光化學(xué)傳感器的可能性。在熒光光譜中鋅(Ⅱ)配合物以及其Pic-離子的聚合物熒光化學(xué)傳感器對H+/OH-的熒光光譜響應(yīng)變化就像開關(guān)一樣,因此得到了繼電傳感器H4L的兩條熒光響應(yīng)鏈:加入(①Zn2+,H+和OH-,②Zn2+,Pic,OH-和H+)離子后溶液的熒光發(fā)生“①關(guān)-開-關(guān)-開”和“②關(guān)-開-關(guān)-開-關(guān)”的變化。
[Abstract]:In many fields, such as scientific research, industrial and agricultural production, environmental protection and so on, the chemical quantity detection and control technology is more and more widely used, and the chemical sensor is the primary link in this process. The research and development of chemical sensors in recent decades show that the application of chemical sensors has penetrated into all aspects of modern life, environmental protection and monitoring, prevention of disasters and diseases. Salen type and Salamo type compounds are multifunctional chelating ligands, their metal complexes are structural chemistry, stereochemistry, magnetics, stereoisomerism, coordination chemistry, etc. Spectroscopy, analytical chemistry, catalysis, optoelectronic display, photography, agriculture, and photochromism play an important role. In this paper, the structure and properties of a long chain Salamo ligand based on naphthalene ring were studied, especially the properties of supramolecular ligands and complexes as fluorescent chemical sensors. Two fluorescent chemical sensors with promising applications have been obtained. The full text is divided into four chapters to discuss: first, this chapter mainly introduces the research background. The development of supramolecular field, including Salen type and Salamo type compounds, fluorescent chemical sensors, the mechanism of host recognition and guest recognition, and representative examples are introduced in this paper. In addition, the significance of the topic is expounded. Secondly, we have designed and synthesized a naphthalene ring bilateral tetraoxime ligand. At the same time, we have obtained the trinuclear metal complexes which react with zinc (鈪，
