Abstract:

It is well known that boronic acids can bind with diols and can be further applied as chemosensors for biomolecules such as carbohydrates and dopamine. Carbohydrates are known to mediate a large number of biological and pathological events. Small and macromolecules capable of carbohydrate recognition have great potentials as research tools, diagnostics, vectors for targeted delivery of therapeutic and imaging agents, and therapeutic agents.

Abstract:

In this work I described and discussed the results of a research project which focused on both development and application of the NMR-chemosensing technique. This technique is based on the combination of gold nanoparticles 2 nm in diameter coated with specific thiols and particular NMR experiments, and it allows to “extract” from the NMR spectrum of a mixture of substances the single NMR spectrum of the analyte bound by the nanoparticle. Specifically, the main goal of my work was to demonstrate how this technique can be successfully used for designer-drug detection. The majority of the new d

Abstract:

The complex photochemical oxidation cycles involved in the degradative removal of anthropogenic and biogenic hydrocarbons from the atmosphere are mediated by a range of radical intermediates (e.g. peroxyl radicals). Thus these radicals are of particular interest in relation to air quality and human health. Speciated measurements of atmospheric radicals pose considerable challenges to analytical chemists. Owing to their low concentrations, high reactivity and short lifetimes, free radical species cannot be easily sampled; therefore direct offline analysis is extremely difficult. Issues such as

Abstract:

Luminescent complexes of lanthanide ions are of growing interest because the long lifetime of emission allows time-resolved detection procedures to be employed. A key step in the development of such systems lies in the preparation of highly luminescent complexes which display high stability in aqueous solution. A series of ligands based on 1,4,7,10-tetraazacyclododecane have been prepared, in which the nitrogen atoms are appended with coordinating phosphinate or amide groups, or a combination of both. The compounds obtained are octadentate ligands which form water-soluble lanthanide complexes

Zinc is now firmly established as an essential trace element in the human body. Whilst it has many key structural and catalytic fixed roles, it is also found in 'mobile' pools in many essential organs and organelles that are readily chelatable. The presence and trafficking of these zinc pools are thought to contribute in some form to many human disease states associated with these organs, for example, Type 2 diabetes in the pancreas, some forms of cancer in the prostate, and even ischemic stroke, epilepsy and Alzheimer's disease. The exact role however, remains largely unknown and this is due

Abstract:

碩士<br>靜宜大學<br>應用化學系<br>105<br>In this thesis, a series of azine derivatives were designed and synthesized as for metal ion chemosensors. UV-Vis spectra showed that 1,2-di(N,N-dimethylaminobenzylidene)hydrazine (3) in acetonitrile and dichloromethane had interactions with silver, chromium, ferrous, ferric, and copper ions. The interaction of azine 3 with ferric ions was most pronounced. Symmetric azine 7 and asymmetric azine 8 showed interactions with copper, cobalt, cadmium, nickel, lead, and zinc ions. At pH 8, both asymmetric azine 8 and symmetric azine 2, 2-hydroxyphenyl azine, exhibited we

碩士<br>國立交通大學<br>應用化學系所<br>97<br>In this thesis, four chemosensors, 2-Methyl-3-[(pyridin-2-ylmethyl)-amino] -1,4-naphthoquinone (1), 2-Methyl-3-(2-pyridin-2-yl-ethylamino)-1,4- naphthoquinone (2), 1-[(Pyridin-2-ylmethyl)-amino]-anthraquinone (3), and 1-(2-Pyridin-2-yl-ethylamino)-anthraquinone(4) were synthesized and evaluated for cation detection. In the binding study of 1 and 2 with transition metal ions, Cu2+ is the only ion caused maximum wavelength shifted from 460 nm (red) to 640 nm (blue). Job’s plot revealed that both sensors 1 and 2 reacted with Cu2+ in a 1:1 stoichiometry. Addition of

Abstract:

碩士<br>國立暨南國際大學<br>應用化學系<br>100<br>Two new fluorescence sensors, namely receptors 3 and 6, incorporating polyether spacer and salicylideneimine moiety have been designed and synthesized. Receptor 3 showed “Off-On” fluorescence signaling behavior for Cd2+. Completing studies showed that the 3-Cd2+ adduct could be replaced by Cr3+, Cu2+, Al3+, Ag+, which would quench the fluorescence. On the basis of titration, Job’s plot and mass spectrum analysis, receptor 3 binds with Cd2+ in a 1:1 stoichiometry with the binding constant K = 5 × 104. Receptor 6 showed “Off-On” fluorescence signaling behavior f

Abstract:

博士<br>國立臺灣大學<br>化學研究所<br>96<br>Part 1: Detection of Phospholipids Base on Chemosensing Ensemble We have previously designed a fluorescence receptor for sensing of phosphate ions. This kind of receptor is established by incorporating four additional amido groups onto pyridine 2,6-biscarboxamide to provide a pseudo-tetrahedral cleft and multiple hydrogen bondings to hold phosphates in a 1:1 complexation stoichiometry. For sensing phospholipids, such as geranyl pyrophosphate (GPP), a modified receptor was synthesized by incorporation of long hydrocarbon chains to increase hydrophobic interaction
