چکیده انگلیسی
The present study deals with synthesis of novel 6-alkoxy-2-amino-3,5-pyridinedicarbonitrile derivatives, as a safety marker. The fluorescence properties of the synthesized heterocyclic compounds were determined. The fluorescence quantum yield (Ïs) of these active compounds, relative to the fluorescence quantum yield of quinine sulfate, is reached at ~Â 0.83. Application of representative synthesized examples on cotton linters and/or bagasse-based paper sheets was adopted in the present study, in an attempt to obtain safety paper from non-wood fibrous pulps. The quality of the obtained safety paper was evaluated based on both fluorescence impact and strength properties. The successful application of these fluorescent active compounds in the production of functionalized paper sheets, from bagasse pulp- cotton linter blend is demonstrated.
