项目摘要

In this study, the mechanism of chemiluminescence was examined by an organic synthetic method in order to explain those that have been unclear. We investigated peroxyoxalate chemiluminescence as well as phthalhydrazide chemiluminescence. Additionally, application of the fluorescent stilbene dyes was also investigated to use them for molecular sensing.The several oxalates with the electron-donating groups caused the intramolecular interaction between the eliminating groups and the high energy intermediates to form the excimers of the phenols, which supports the important role of the electronic interaction such as a CIEEL process during peroxyoxalate chemiluminescence,The reactions of 4-styrylphthalhydrazides revealed that the chemiluminescence behavior was highly dependent on the electronic nature of the substituents. The strongly electron-donating groups increased the fluorescence quantum yields of the emitters, phthalic acid anions, resulting in enhancement of the chemiluminescence in … More tensities. Control of the chemiluminescence feature by such the effect provides a new finding in the phthalhydrazide chemiluminescence.To develop a molecular sensing using chemiluminescence, the strongly fluorescent distyrylbenzenes were examined for the use as the fluorophores that reflect the change in the microenvironment around them. The pull-push type of distyrylbenzenes responded toward various protic solvents, water and alcohols, to be fluorescence-quenched. The close relation between the fluorescence-quenching efficiency and the pKa values of the solvent was established, which might provide the sensor of the substrates with protic characters.Organic chloro- and nitro compounds that are harmful residues of agricultural chemicals and explosives also quenched the strongly fluorescent distyrylbenzenes with the strongly electron-donating substituents. Phenylboronic acid and calcium ion also quenched the fluorescence of these distyrylbenzenes. Such fluorescence quenching was due to the photo-induced electron transfer (PET) process.Thus, this study provides some new aspects useful to develop the organic chemiluminescence. Less
本研究通过有机合成方法对化学发光的机理进行了研究,以解释那些尚不清楚的问题。我们研究了过氧草酸盐化学发光以及邻苯二甲酰肼化学发光。此外,还研究了荧光二苯乙烯染料的应用,以将其用于分子传感。几种带有给电子基团的草酸盐引起消除基团与高能中间体之间的分子内相互作用,形成酚类准分子,这支持了电子相互作用(例如过氧草酸盐化学发光过程中的CIEEL过程)的重要作用, 4-苯乙烯基邻苯二甲酰肼表明化学发光行为高度依赖于取代基的电子性质。强给电子基团增加了发射体邻苯二甲酸阴离子的荧光量子产率,从而增强了化学发光强度。通过这种效应控制化学发光特征为邻苯二甲酰肼化学发光提供了新的发现。为了开发利用化学发光的分子传感,研究了强荧光二苯乙烯基苯作为反映其周围微环境变化的荧光团的用途。推拉型联苯乙烯苯对各种质子溶剂、水和醇有反应,从而被荧光猝灭。建立了荧光猝灭效率与溶剂pKa值之间的密切关系,这可能为基材的传感器提供质子特性。农用化学品和炸药的有害残留物有机氯代和硝基化合物也会猝灭具有强给电子取代基的强荧光二苯乙烯基苯。苯基硼酸和钙离子也猝灭这些二苯乙烯基苯的荧光。这种荧光猝灭是由于光诱导电子转移(PET)过程造成的。因此,本研究为有机化学发光的发展提供了一些新的方面。较少的
