Sensing and optical activities of new pyrazole containing polymeric analogues
The semi-linear pyrazole containing polymeric structures have been synthesized by three different methods to produce 4-(4-(phenyldiazenyl)-1
H -pyrazole-3,5-diyl)oligomer, copolymer and homopolymer analogous with molecularweight up to 24000 g mol$^{–1}$. Thermogravimetric analysis showed that the copolymer and homopolymer analogous have high thermal stability than the oligomer. The photoluminescence behaviour and sensing application of the new compounds were analysed by UV–visible spectroscopy and fluorescence spectroscopy. The copolymer analogue was found to show high sensitivity to acetate anion.
