【摘要】 设计合成了一个5,15-meso-meso冠醚修饰的卟啉1(化合物1)作为荧光开关的模型化合物,选择Cu+离子作为淬灭剂,激发该化合物不同发光单元时,分别记录化合物1的荧光淬灭效果,发现不同激发光的使用可以调节激发电子的流向,同时有效地表现出Cu+离子调控下的荧光开关性能.文中对目标化合物进行了详细的表征,同时对化合物1的开关性能进行了合理的解释.更多还原

【Abstract】 A crown ether modified 5,15- meso,meso- porphyrin 1,as a model compound of a fluorescence switch,was designed and synthesized,and Cu+ion was selected as quencher to investigate its switch effect. It was founded that the direction of excited electron transfer can be adjusted through changing the stimulation to different light- emitting components in the compound,and also display effective fluorescence switching property under the regulation of Cu+ions. The target compound 1 was delibratively characterized and its switching properties were reasonablly explained.更多还原
