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

摘要

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.
