简介：摘要以葫芦脲为主体的超分子化学近年来得到了快速发展,目前已成为超分子化学中最为活跃的研究领域之一,许多无荧光或弱荧光物种采用传统的荧光分析方法无法实现荧光测定,因此使之在药代动力学监测和痕量测定方面变得十分困难.近年来,通过建立的新型荧光探针体系葫芦脲－异喹啉类药物使许多无荧光的药物建立了高灵敏度的分析方法.本论文旨在借助这一新型荧光探针体系,采用荧光光谱法、核磁共振波谱法、密度泛函理论等手段从实验和理论两个方面研究了盐酸克伦特罗与葫芦脲主－客体之间的相互作用,确立了这一探针体系与目标分析物的作用机理,建立了无荧光的盐酸克伦特罗的荧光探针新方法.关键词葫芦７脲,克伦特罗,荧光滴定法,荧光探针AbstractInrecentyears,withtherapiddevelopmentofthesupramolecularchemistryofthemainbodyoftheurea,themostactiveresearchfieldsofthesupramolecularchemistryhavebecomeoneofthemostactiveresearchfields．Inrecentyears,anewtypeoffluorescentprobesystemhasbeenestablishedfortheestablishmentofahighsensitivityanalysismethodformanynonfluorescentdrugs．Thisthesisisforthepurposeofusingthisnovelfluorescentprobesystem,clenbuterolandcucurbiturilhostguestinteractionswasstudiedfromtheaspectsofexperimentandtheorybymeansoffluorescencespectroscopy,nuclearmagnetＧicresonancespectroscopy,densityfunctionaltheory,establishthemechanismoftheprobesystemwithatargetanalyte,nofluorescenceofclenbuterolhydrochloＧridefluKoeryeswcoerndtsprobemethodwasestablished．cucurbit７uril,clenbuterol,fluorescencetitration,fluorescenceprobe中图分类号R９６文献标识码B文章编号１００８－６３１５(２０１５)１２－０４０２－０２
