Reversible Colorimetric and Fluorescence Solid Sensors Based on Aryl Hydrazone Derivatives of 1,8-Naphthalimides for Caustic Media and Biogenic Amine Vapors

Fluorescence and colorimetric solid sensors for caustic media biogenic amine vapors have been prepared. For this purpose, several hydrazone derivatives of naphthalimides were synthesized anchored to a photo-crosslinked membrane functionalized with acid chloride groups. The membranes characterized using different techniques, their thermal properties swelling degree determined. new the evaluated as by determining change in spectroscopic absorption fluorescence pH. polymeric exhibit improved stability can be reused, consequence character reversibility process. Furthermore, sensor trimethylamine through bands, color showed that it could used detect basic naked eye. Finally, packaged Petri dishes at controlled temperature fresh fish bought local market. Then, real chance sensory materials was determined analyzing samples.
