Abstract

ONE OF THE MOST EFFECTIVE CLICK REACTIONS AT THE PRESENT IS THE HUISGEN 1, 3- DIPOLAR CYCLOADDITION REACTION OF AZIDES AND TERMINAL ALKYNES CATALYZED BY COPPER (I) COMPLEXES. THE COUPLING OF AN AZIDE AND A TERMINAL ALKYNE BY A CU (I) CATALYZED 1, 3-DIPOLAR CYCLOADDITION REACTION LEADS TO THE SELECTIVE FORMATION OF A 1, 4 DISUBSTITUTED TRIAZOLE RING, A CHEMICALLY VERY STABLE COMPOUND. THIS REACTION HAS MANY ADVANTAGES INCLUDE LOW REACTION TEMPERATURE, SIMPLE AND INEXPENSIVE CATALYST, SOLVENT TOLERANCE, HIGH SELECTIVITY, HIGH PURITY AND QUANTITATIVE YIELD OF THE REACTION [1-2].IN THIS PAPER, A NEW DIALKYNE-TERMINATED MONOMER WAS SYNTHESIZED AND USED IN THE CLICK REACTION WITH VARIOUS ALKYL DIAZIDES TO PRODUCE POLY (TRIAZOLE-ETHER-IMIDAZOL) S (PTAEI). A SERIES OF NANOCOMPOSITES WAS PREPARED FROM SOLUTION BLENDING OF PTAEIS WITH EPOXIDE-END CAPPED CLAY NANOPARTICLES. INCLUSION OF FUNCTIONAL GROUPS SUCH AS TRIAZOLE AND IMIDAZOLE IN THE POLYMER CHAINS ARE CAUSED TO IMPART EXCEPTIONAL PROPERTIES INCLUDING SOLUBILITY, THERMAL AND PHOTOPHYSICAL AND ALSO THESE FUNCTIONALIZED POLYMERS AND PARTICULARLY THEIR NANO COMPOSITES CANACT EFFICIENTLY AS CHELATING AGENT FOR THE REMOVAL OF HEAVY METAL IONS FROM AQUEOUS SOLUTION. THE RESULTING POLYMER AND THE NANO COMPOSITES WERE CHARACTERIZED BY USING FT-IR, 1HNMR AND TEM AND THEIR PROPERTIES SUCH AS SOLUBILITY, THERMAL, PHOTOPHYSICAL AND THEIR ABILITY FOR REMOVAL OF ENVIRONMENTALLY TOXIC HEAVY METAL IONS WERE INVESTIGATED.
