    We report about new syntheses and improvements in the preparation of monomers which are necessary in the syntheses of conjugated organic materials and polymers. First, the synthesis of a phosphorescent iridium containing monomer, such as the 9-(2,7-dibromocarbazol-9-yl)nonan-2,4-dionato-bis(2-phenylpyridine-N,C2’)iridium(III) complex, is reported. Second, the preparation of a monomer for Suzuki coupling, the 9-(2-ethylhexyl)-2,7-bis-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)carbazole, was improved and compared with previous procedures. Finally, the synthesis of two silicon containing monomers, the 4-(2-ethylhexyl)-4′-octyl-5,5′-bis(trimethylstannyl)di-thieno[3,2-b:2′,3′-d]silole and the 2,7-bis-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-9,9'-bis(2-ethylhexyl)dibenzosilole, based on dithienosilole and dibenzosilole structural unit, respectively, was proposed. The synthesis of silicon containing polymer, poly[4,6-bis(3-dodecylthien-2-yl)thieno[3,4-c][1,2,5]thiadiazole-alt-4-(2-ethylhexyl)-4′-octyldithieno[3,2-b:2′,3′-d]silole is reported as well.
