The invention relates to the receptor it is the novel cholestane -based fluorescence which selectively reacts to the organic acid the pyrene group is bound as the fluorescence having the selectivity in the organic acid the receptor and a manufacturing method thereof in the imidazole -based cholestane introducing the imidazole to more detailed cholestane skeleton and manufacturing method thereof. By showing the organic acid, especially, the oxalic acid and high binding affinity the receptor has the effect that it selectively senses and the receptor can use in the sensing of the oxalic acid whether it is the imidazole -based cholestane …
Pyrene Appended Imidazole Compound And Selective Fluorescence Sensing Of Aromatic Carboxylic Acids Using The Same (파이렌-이미다졸기가 연결된 화합물 및 이를 이용한 방향족 카르복실산의 선택적 형광인지), Hong Seok Kim, Md Wasi Ahmad

The invention relates to the novel compound and the manufacturing method thereof, and the benzoic acid derivative and the salicylic acid derivative composition for detecting using the same. The novel compound of the present invention is comprised of the pyrene and imidazole. And it hydrogen-bonds with the compound which the imidazole part detects. It interacts with the benzene ring and strong π - π of the compound which the pyrene part detects and the fluorescence intensity is changed the aromatic carboxylic acid can be recognized.
Selective Fluorescence Sensing Of Salicylic Acid Using A Simple Pyrene Appended Imidazole Receptor, Md Wasi Ahmad, Bo Yeon Kim, Hong Seok Kim
Selective Fluorescence Sensing Of Salicylic Acid Using A Simple Pyrene Appended Imidazole Receptor, Md Wasi Ahmad, Bo Yeon Kim, Hong Seok Kim
Dr. Mohammad Wasi Ahmad (Md Wasi Ahmad)
A simple salicylic acid selective fluorescence receptor 1 was designed by combining 1-pyrenecarboxaldehyde and 1-(3-aminopropyl)imidazole. The selective sensing of salicylic acid resulted in a significant increase in monomer emissions due to the p–p interactions between the benzene and pyrene rings. The nature of the interactions between receptor 1 and salicylic acid was investigated further by 1H NMR spectroscopy, and the energy minimised structure of the complex between receptor 1 and salicylic acid was optimised. Receptor 1 showed the highest binding constant with 5-nitrosalicylic acid among all the aromatic carboxylic acids tested. 5-Nitrosalicylic acid formed a complex with receptor 1 at …
