Full textThis thesis deals with the peroxyoxalate chemiluminescence (POCL) reaction and its application as a detection technique in flow systems for chemical analysis. Particularly, miniaturized flow systems aimed for separation of molecules. In such systems, a high light intensity and a rapid development of the emission are the desired reaction characteristics, for reasons discussed in this text. The work tries to develop an understanding of the chemical processes involved in POCL, with special emphasis to the species favoring or hindering a rapid light evolution. Hence, is the focus placed on the nature of catalysis and the desired properties of substances acting as catalysts in this reaction. Consequently, the scientific papers on which this work is founded includes both systematic stopped-flow studies of catalyst candidates and of the causes for diminished light emission. In addition, multivariate strategies for reaction optimization in practical analysis situations are treated, and the application of the POCL technique to detection of serum-extracted neuroactive steroids, derivatized with fluorescent moieties, is presented.
From the experiments in this thesis it is clear nucleophilic catalysts are the most efficient enhancing compounds, which means that they must possess a carefully balanced characteristics of nucleophilicity, leaving group ability, and basicity. The investigations also conclude that the feature of basicity efficiently can be delegated to a non-nucleophilic co-catalyst, which allow the use of nucleophilic catalysts that need to be deprotonated to be active. This thesis also shows the importance of minimizing the amount of competing nucleophiles at the site of reaction to maintain the emission. This implies that also solvents and buffer substances should be carefully chosen not to interfere with the emission process.
The most promising combination of catalysts found in this work was 4,5- dichloroimidazole together with 1,2,2,6,6-pentamethylpiperidne. This arrangement was capable of speeding the reaction more than tenfold while increasing the maximum emission intensity by about the same factor.

Full textElectrogenerated chemiluminescence (ECL) involves the energetic electron transfer reactions at the electrode with the generation of excited state of emitter, which then relax to the ground state and emit light. These ECL reactions can be divided into two main pathways: the annihilation and sacrificial co-reactant reactions. The latter has found a lot of applications in analytical chemistry. In this thesis, ECL studies towardt hree complementary directions are presented, ranging from the molecular scale tomacroscopic scale : the research of new ECL luminophores, the study of stimuli-responsive hydrogel films, and the development of new ECL assays.Firstly, I have studied three types of organic dyes for ECL investigations. These organic dyes exhibit interesting electrochemical and ECL properties. ECL efficiencies of the organic dyes can be tuned by the modification of the structures. Spirofluorene dyes show strong ECL emission, and thus its fluorescence organic nanoparticles(FONs) prepared in water were used as ECL nano-emitters. We also established an energetic ECL “wall” representation and then move forward creating ECL “map”upon electrochemical, photoluminescence and ECL studies on cationic triangulenes and cationic helicenes dyes, respectively.Secondly, the preparation of thermo-responsive poly(N-isopropylacrylamide)(pNIPAM) hydrogel films covalently incorporating Ru(bpy)3 redox centers were achieved on glassy carbon electrode (GCE) or carbon fiber by electrochemically induced free radical polymerization. ECL studies on the modified GCEs have provided the main factor (the average distance of Ru(bpy)3 sites) that governs the ECL process, leading to deciphering the enhanced ECL in the films. The deposition of the films on carbon fiber by bipolar electrochemistry (BPE) has opened new route to for the development of smart hybrid micro objects. Finally, analytical application is one of the most important features of ECL. We presented two different ECL assays using either the phenylboronic acid modified amine based co-reactants or gold coated optical fiber bundle. The binding of saccharides with boronic acid modified tertiary amines makes the oxidation of amines group inefficient, which decreases ECL signal response. By changing linker length of a bis-boronic acid amine co-reactant, we are able to determine D-glucose and D-fructose selectively. We also studied the ECL generation of Ru(bpy)32+/TPrA systemon the gold coated optical fiber bundle in a wireless manner by BPE, then transmission and remote detection at the opposite end of the same object. This methodmay extend the applicability of ECL assays in the confined or hazardous environments
电化学发光(ECL)的发生是由于在电极表面通过电子转移反应生成了发光体的激发态跃迁到基态,并伴随着发光。这些电子转移反应可划分为两种主要的途径:正负自由基湮灭反应和共反应物反应。而后者被广泛应用于分析化学领域。在本论文中,我们在电化学发光领域中进行了广泛的研究,具体有三个研究方向:新型电化学发光光团的研究、响应水凝胶膜的制备以及电化学发光分析的研究。首先,我们选择了三种不同类型的有机荧光分子用于电化学发光的研究。这些有机荧光分子展现出许多电化学和电化学发光特性。其中,螺芴荧光分子展现出了非常强的电化学发光。而且用它制备的荧光有机纳米颗粒(FONs)在水相中也可以产生电化学发光。基于对阳离子型三角烯和阳离子型螺烯的电化学、光谱学以及电化学发光的研究,我们分别建立了鉴别电化学发光“墙”和“图谱”。其次,利用自由基电聚合的方法,我们实现了在玻碳电极和碳纤维表面上制备热刺激-响应的聚异丙基丙烯酰胺(p-NIPAM)共价嫁接三联吡啶钌Ru(bpy)3 荧光分子的水凝胶膜。通过对玻碳电极上水凝胶膜的电化学发光的研究,我们发现了控制水凝胶膜中电化学发光的主要因素,从而揭秘了水凝胶膜中电化学发光增强的成因。而且,利用双电极化学(BPE)的方法,我们将此类水凝胶膜的制备应用于碳纤维上,以发展灵敏杂化微米级器件。最后,鉴于化学分析是电化学发光最重要的特征,我们构建两种不同的电化学发光分析体系:一种是基于硼酸化学修饰的三丙胺共反应物;另一种是利用镀金光导纤维。硼酸对糖类的结合弱化了三丙胺的电化学氧化效率,因此影响电化学发光的强度。通过改变双硼酸修饰共混物之间碳链的长度,我们实现了对葡萄糖和果糖的选择性检测。我们还研究了在镀金光导纤维上三联吡啶钌/三丙胺体系的 电化学发光。此研究是在双电极体系进行的,镀金光导纤维无需外部接线,镀金部位产生的发光透过光纤传输的光纤的远端,再进行检测,因此达到了电化学发光的远程检测。这一方法可应用于狭窄危险环境中的电化学发光分析。

Full textElectrogenerated chemiluminescence (ECL) is a powerful analytical technique exploited for clinical, industrial and research applications. The high sensitivity and good selectivity, makes ECL a tool-of-choice analytical method for a broad range of assays, most importantly for a large number of commercialized bead-based immunoassays. In the present thesis, we aimed to study the ECL phenomenon and its application in development of new analytical methods.In the first part of this work, we used an imaging technique to investigate the ECL mechanisms operating in bead-based assays. Spatial reactivity mapping at the level of a single functionalised bead provides a new strategy to test the co-reactant efficiency and shows associated optical focusing effects.In the second part, the design of a novel anti-transglutaminase ECL immunoassay for celiac disease diagnostic is shown using nanoelectrode ensembles as bioelectroanalytical platforms. We also studied the characteristics of ECL generated by arrays of boron-doped-diamond nanoelectrodes (BDD NEAs) as a promising materials for bioapplications. The ECL efficiency of two co-reactants at BDD NEAs was investigated.Finally, bipolar electrochemistry is a ‘‘wireless’’ process that was exploited for the controlled motion of conductive objects exposed to an electric field in the absence of direct ohmic contact. In the third part of the thesis, we report ECL coupled to bipolar electrochemistry for tracking the autonomous trajectories of swimmers by light emission. We further expanded this concept for dynamic enzymatic sensing of glucose concentration gradient using ECL light emission as an analytical readout
