Series of novel polymeric chemosensor systems based on poly(4-vinyl)pyridine and its copolymer with poly(buthylmethacrilate) were synthesized. Initial polymers were modified by introduction in their framework of fragments containing receptor and signaling centers. Structure, main characteristics and ionochromic properties were investigated by spectral methods. Synthesized compounds reveal weak fluorescence and intense chemosensor activity towards anions. Interaction with F- and AcO- leads to strong increase of fluorescence intensity. Chemosensors synthesized by modification of poly(4-vinyl)pyridine - poly(buthylmethacrilate) copolymer are the most effective and selective fluorogenic systems for fluoride anions detection. These compounds at the same time display effective chromogenic activity for F- and CN-recognition.
