Nickel–sodium pyrene tetrasulfonic acid based co-ordination polymer as fluorescent template for recognition of azo dyes

Pyrene tetrasulfonic acid based co-ordination polymer (Na–Ni–PTS) with nickel and sodium as metal ions is synthesized. The fluorescent polymer Na–Ni–PTS is utilized as template for recognition of industrially relevant azo dyes BY (Brilliant yellow), AYGG (Alizarin yellow GG), MO1 (Mordant orange 1), TONa (Tropaeolin O sodium salt), MO (Methyl orange), PAP (4-Phenylazophenol), SII (Sudan II), OG (Orange G), AB (Azobenzene). It was observed that most of the azo dyes quenched the fluorescence Na–Ni–PTS. The practical application of Na–Ni–PTS as azo dye sensor was observed using a fabric on which BY was absorbed and also by mixing of BY with food stuff.
