Several methods have been developed to synthesize carbon-rich materials. One of the most efficient method is oxidative cyclodehydrogenation of planary three-dimensionnal dendritic oligophenylene derivatives. Materials obtained by this method usually have good electronics properties which allow their use in electronic and optoelectronic transistors.Our method uses cycloaromatization of polydiacetylenes (PDAs) and polytriacetylenes (PTAs) derivatives activated by temperature, light or catalysts.  PDAs are synthesised by topochemical polymerization of 1,4-diphenylbutadiynes derivatives in the solid and gel states using 254 nm UV light. PTAs are obtained via Glaser coupling of triacetylene derivatives bearing terminal alkynes.The materials obtained were characterized using different techniques including UV-Visible, fluorescence, NMR and raman spectroscopies as well as SEM et TEM imaging. These studies provide good understandings of such materials for potential use in electronic and optoelectronic devices.,
