This work reports selective polyamidation of a diamine-phenol compound (3) in an ionic liquid (IL) and preparation of transparent composites from the obtained high performance polyamides (PA) s and modified gamma-Al2O3 nano-particles (m gamma NAl). The PAs were prepared selectively from polycondensation of compound 3 with several dicarboxylic acids in the mixture of (IL)/triphenylphophite(TPP). The fluorescent PAs (lambda(em)=500 nm) exhibited glass transition (T-g) and 10 % weight loss temperatures (T-10%) in the range of 188-325 degrees C and 447-511 degrees C, respectively. The structurally intercalated composites (NCPA) s were prepared from PAs and epoxide-functionalized gamma-Al2O3 (m gamma NAl) via solution blending process. The strong chemical bonding between m gamma NAl and PA chains contributed to the enhanced thermal and mechanical properties of the composites. Also, the photoluminescence intensity increased with increasing m gamma NAl content. The PAs and composites were also tested for their extraction capability for environmentally deleterious metal ions from aqueous solutions either individually or in the mixture.
