中文摘要：
设计并合成了一种可用于识别的Cu^2＋新型荧光探针（3＇,6＇-双（二乙氨基）-2-（4-（二乙氨基）-2-羟基苯胺基-螺（异喹啉-1,9＇-氧杂蒽）-3-酮）（RB）。通过红外、元素分析、质谱、-1HNMR、-（13）CNMR等手段表征了探针的结构。其光谱性和离子选择性实验结果表明,RB自身荧光很弱,但是与Cu^2＋结合后会发生显著的荧光增强,而与其他金属离子结合后,荧光强度变化很小。说明RB对Cu^2＋具有很好的选择性和较高的灵敏度,可用作Cu^2＋荧光增强型探针,据此建立了一种测定Cu^2＋的新型分析方法。
英文摘要：
3＇,6＇-bis（ diethylamino）-2-（ 4-（ diethylamino）-benzylideneamino） spiro[isoindoline-1,9＇-xanthen]-3-one（ RB） was designed and synthesized for identifyingCu^2＋. The structure of the probe was confirmed by infrared spectroscopy,elemental analysis,MS,1HNMR,13 CNMR. Based on the spectrum and ions selective experiment results show that,probe L auto fluorescence is weak,but whenCu^2＋binding the fluorescence will be significantly enhanced. The experimental results showed that,a probe L forCu^2＋has a good selection and high sensitivity,thereby establishing a new approachCu^2＋measured.
