Clicked-polymer-derivedceramics (cPDC) were elaborated using no chromatographic purification steps. Starting from suitable monomers ,three original silicon-contained clicked-polymers P1-3 were synthe- sized in good yields, using the copper-catalyzed azide-alkyne cycloaddition (CuAAC). Then, the thermal behaviors of the organic materials were investigated until 1400 1C. Thank stoXRD analysis, an α-SiC was unusually observed for materials obtained from P1 and P2. Thereby, pyrolysis of polymer P3 led toa composite α-SiC-ZrC. The free carbon, initially observed after pyrolytic treatmentof P1 and P2, was removed in the final material C3. A structure for P3 was then proposed on the evidence of IR and NMR spectroscopic data. Hence, the polymer-derived ceramics route was synergistically associated to the CuAAC to generate high performance materials.
