【摘要】：材料對(duì)人們生產(chǎn)生活有著革命性的引領(lǐng)作用,因此材料的研究越來(lái)越熱,尤其自組裝材料和智能材料是近幾年研究的熱點(diǎn)內(nèi)容。自組裝避免了復(fù)雜的有機(jī)合成,智能材料對(duì)環(huán)境起一定的感知、反應(yīng)、自調(diào)節(jié)作用,這些不劇烈的、緩慢的、柔和的反應(yīng),更接近于生命的生理過(guò)程,具有很大的研究前景和價(jià)值。預(yù)膠束和膠束也屬于自組裝的范疇,但人們卻對(duì)預(yù)膠束的領(lǐng)域研究很少,尤其是在國(guó)內(nèi)。預(yù)膠束作為膠束形成之前的一個(gè)狀態(tài),對(duì)環(huán)境的變化敏感而且做出響應(yīng),各項(xiàng)性能都與膠束有很大差異,都有待探討。本文致力于研究熒光試劑與表面活性劑各濃度比例下的自組裝,主要探討預(yù)膠束濃度范圍內(nèi)自組裝和智能響應(yīng)。通過(guò)高分辨率透射電子顯微鏡、紫外-可見(jiàn)吸收光譜、熒光發(fā)射光譜、熒光壽命、電化學(xué)循環(huán)伏安法等多種手段探究熒光試劑中性紅分別與表面活性劑十二烷基磺酸鈉、十二烷基苯磺酸鈉混合時(shí)的形貌,光譜性能以及對(duì)外界環(huán)境的響應(yīng)能力,得出一系列相關(guān)結(jié)論。具體研究工作包括以下幾個(gè)方面:1、本文研究了中性紅在堿性條件下稍高的濃度范圍內(nèi),通過(guò)紫外-可見(jiàn)吸收光譜、熒光發(fā)射光譜、超高分辨透射電子顯微鏡多種手段探討其自組裝行為。中性紅在中性和堿性環(huán)境中,大量轉(zhuǎn)化為中式型體,該型體疏水性強(qiáng),因此發(fā)生自我聚集和組裝的能力大大增強(qiáng),在疏水性、π-π堆積等多種分子間作用力的協(xié)同作用下,發(fā)生自組裝,且加熱也不能使這種組裝逆轉(zhuǎn),因此,中性紅對(duì)酸堿的響應(yīng)很靈敏,在堿性環(huán)境中自組裝能力很強(qiáng)。2、本文研究了中性紅與十二烷基磺酸鈉的自組裝體系,且比例不同可以形成不同的形貌:沉淀、囊泡、膠束。探討比例、濃度等多方面因素對(duì)體系光譜性能的影響,并首次用超高分辨透射電子顯微鏡觀察了此種自組裝體系的微觀形貌,利用循環(huán)伏安表征該體系的氧化還原性能,同時(shí)也探討了此自組裝體系對(duì)pH、溫度和金屬離子的響應(yīng)。3、本文研究了中性紅與十二烷基苯磺酸鈉的自組裝體系,比例不同可以形成不同的形貌:沉淀、纖維、膠束。和中性紅與十二烷基磺酸鈉形成對(duì)比,中性紅與十二烷基苯磺酸鈉發(fā)生自組裝主要通過(guò)疏水作用力誘導(dǎo)、π-π堆積和靜電的影響,比中性紅和十二烷基磺酸鈉的結(jié)合力強(qiáng),因此體系更穩(wěn)定。也探討比例、濃度等多方面因素對(duì)體系光譜性能的影響、并用超高分辨透射電子顯微鏡觀察了此種自組裝體系的微觀形貌,利用循環(huán)伏安表征該體系的氧化還原性能,也研究了自組裝體系對(duì)金屬離子、p H和溫度的響應(yīng)。4、本文合成了中性紅和十二烷基磺酸鈉濃度較濃時(shí)形成的凝膠體系。探究此凝膠體系形成的最佳條件,例如濃度配比、pH、溫度、鹽、表面活性劑種類(lèi)等,并進(jìn)行了機(jī)理探討即依靠靜電作用、氫鍵、鏈的纏繞形成的非永久性的熱可逆凝膠,對(duì)研究凝膠材料和制作凝膠與智能材料奠定一定的理論基礎(chǔ)。
[Abstract]:Materials have a revolutionary leading role in people's production and life, so the research of materials is becoming more and more hot, especially self-assembled materials and smart materials are hot topics in recent years. Self-assembly avoids complex organic synthesis, smart materials have a certain sense, reaction, self-regulation of the environment, these nonviolent, slow, soft reactions are closer to the physiological processes of life. It has great research prospect and value. Premicelles and micelles also belong to the category of self-assembly, but there are few researches on premicelles, especially in China. As a state before micelle formation, premicelles are sensitive to and responsive to environmental changes. The properties of premicelles are very different from those of micelles, which need to be discussed. In this paper, the self-assembly of fluorescent reagents and surfactants at different concentrations is studied, and the self-assembly and intelligent response in the concentration range of premicelle are mainly discussed. Fluorescence reagent neutral red and surfactant sodium dodecyl sulfonate were investigated by means of high resolution transmission electron microscope, UV-Vis absorption spectrum, fluorescence emission spectrum, fluorescence lifetime, electrochemical cyclic voltammetry, etc. The morphology, spectral properties and responsiveness to the environment of sodium dodecylbenzene sulfonate were studied and a series of conclusions were obtained. The specific research work includes the following aspects: 1. In this paper, we have studied the fluorescence emission spectrum of neutral red in the range of slightly higher concentration under alkaline condition through UV-Vis absorption spectrum, The self-assembly behavior of ultrahigh resolution transmission electron microscope (UHTEM) was investigated by various means. Neutral red is transformed into Chinese type in neutral and alkaline environment, which has strong hydrophobicity, so the ability of self-aggregation and assembly is greatly enhanced by the synergistic action of hydrophobicity, 蟺-蟺 stacking and other intermolecular forces. Self-assembly occurs, and heating can not reverse the assembly. Therefore, neutral red is sensitive to acid-base and has strong self-assembly ability in alkaline environment. 2. The self-assembly system of neutral red and sodium dodecyl sulfonate has been studied in this paper. And different proportion can form different morphology: precipitate, vesicle, micelle. The effects of various factors, such as ratio and concentration, on the spectral properties of the system were discussed. The micromorphology of the self-assembled system was observed by ultrahigh resolution transmission electron microscope for the first time, and the redox properties of the system were characterized by cyclic voltammetry. At the same time, the response of the self-assembly system to pH, temperature and metal ions is also discussed. 3. The self-assembly system of neutral red and sodium dodecylbenzene sulfonate has been studied in this paper. Different proportions can form different morphologies: precipitate, fiber and micelle. In contrast with neutral red and sodium dodecyl sulfonate, the self-assembly of neutral red and sodium dodecyl benzene sulfonate is mainly induced by hydrophobic force, 蟺-蟺 accumulation and electrostatic effect, which is stronger than that of neutral red and sodium dodecyl sulfonate. As a result, the system is more stable. The effects of various factors, such as ratio and concentration, on the spectral properties of the system were also discussed. The micro-morphology of the self-assembled system was observed by ultrahigh resolution transmission electron microscope, and the redox performance of the system was characterized by cyclic voltammetry. The response of the self-assembled system to, p H and temperature of metal ions was also studied. 4 the gel system of neutral red and sodium dodecyl sulfonate was synthesized when the concentration of neutral red and sodium dodecyl sulfonate was high. The optimum conditions for the formation of this gel system, such as concentration ratio, pH, temperature, salt, surfactant species and so on, were investigated. The mechanism of the formation of the non-permanent thermoreversible gel by electrostatic interaction, hydrogen bond and chain winding was discussed. It lays a theoretical foundation for the study of gel materials and the manufacture of gel and smart materials.
