چکیده
|
In this paper, 4-amino-7-methoxy-2-oxo-2h-spiro[acenaphthylene-1,2-chromene]-3-carbonitrle and their derivatives were synthesized via three-component reaction in the presence of fe3o4@sio2@si-pr-nh(ch2)2nh2 catalyst the spectra absorption of synthesized compound was analyzed in the presence of various anions (cl-, cn-, scn-, br-, f-, oh-, ch3coo-, i-, cr2o72-, hso3-, hso42-, co32-, hpo42-, no2- and no3-) by uv-visible spectroscopy in ch3cn solvent. the sensing properties of 4-amino-7-methoxy-2-oxo-2h-spiro[acenaphthylene-1,2-chromene]-3-carbonitrle were studied, which was demonstrated highly selective activity towards cn- ions in ch3cn.
