Design and Synthesis of Dual Fluorescent Neutral Receptors for Molecular Recognition

Abstract

分子识别是超分子化学的核心研究内容之一,包括离子客体和中性分子的识别。由于荧光检测的高灵敏度和可实时及远程检测等优越性,在分子识别与传感中的应用得到蓬勃发展,设计合成高灵敏、高选择性的荧光化学传感器近年来备受关注。具有分子内电荷转移和激发态质子转移性质的荧光体,发射大Stokes位移的荧光,可消除基质本底荧光和散射光对化学传感和分子识别的潜在不利影响。为此,本论文拟以具有分子内电荷转移双重荧光的对二甲氨基苯甲酰胺衍生物和分子内质子转移的水杨醛衍生物为荧光信号报告基团,耦合阳离子或阴离子识别位点,设计合成了系列荧光化学传感器。论文共分六章。第一章:从分子识别原理上概述了荧光传感器的研究进展,并提...Molecular recognition is an important subject in supramolecular chemistry. Design and synthesis of fluorescent chemsensor have drawn much interests in supramolecular chemistry in recent years due to its intrinsic distinct advantages in terms of high sensitivity, able to monitor substrate concentration in real-time and real-space and remote sensing. Intramolecular charge transfer (ICT) or intramole...学位:理学博士院系专业:化学化工学院化学系_分析化学学号:B20012500
