Abstract A fluoranthene based fluorescent chemosensor 2-(7,10-diphenyl-fluoranthen-8-yl)-pyridine ( B ) which shows excellent selectivity towards Fe 3+ is described. Upon addition of FeCl 3 into the ethanol solution of B , it exhibits a great decrease of emission intensity against environmental and biological samples. Further experiments demonstrate that Fe(NO 3 ) 3 has the similar influence as FeCl 3 on the emission spectra of B while Fe 2 (SO 4 ) 3 has no influence on that of B .

基于荧蒽的吡啶作为 Fe3+ 的荧光化学传感器

摘要 描述了一种基于荧蒽的荧光化学传感器 2-(7,10-diphenyl-fluoranthen-8-yl)-pyridine (B)，它对 Fe 3+ 表现出优异的选择性。在B 的乙醇溶液中加入FeCl 3 后，它对环境和生物样品的发射强度大大降低。进一步的实验表明，Fe(NO 3 ) 3 对B的发射光谱具有与FeCl 3 相似的影响，而Fe 2 (SO 4 ) 3 对B的发射光谱没有影响。
