The present work aims at elaborating new polymers by copper (I)-catalyzed azide-alkyne cycloaddition (CuAAC) step growth polymerization suited for the storage of alternative energies. In a first part, the AA+BB CuAAC polyaddition has been investigated using several difunctional monomers to prepare norbornadiene-containing poly(1,2,3-triazole)s. The norbornadiene units present in the main chain of these polymers are isomerized after UVirradiation into quadricyclane units able to store solar energy. In a second part, other linear poly(1,2,3-triazole)s were prepared from α-azide-ω-alkyne heterofunctional monomers. The post-polymerization chemical modification of these poly(1,2,3-triazole)s (quaternization of the 1,2,3-triazole units followed by anion metathesis reaction) resulted in new 1,2,3-triazolium-based poly(ionic liquid)s (TPILs). Various TPILs were obtained and their ionic conductivity properties were studied by dielectric spectroscopy. Finally, a UV-crosslinkable poly(1,2,3-triazolium) was synthesized and was used as a negative tone photoresist for lithography thus affording the efficient patterning of solid electrolytes
