A fluoranthene based fluorescent chemosensor 2-(7,10-diphenyl-fluoranthen-8-yl)-pyridine (B) which shows excellent selectivity towards Fe³⁺ is described. Upon addition of FeCl₃ into the ethanol solution of B, it exhibits a great decrease of emission intensity against environmental and biological samples. Further experiments demonstrate that Fe(NO₃)₃ has the similar influence as FeCl₃ on the emission spectra of B while Fe₂(SO₄)₃ has no influence on that of B.
