A family of structurally related pi-conjugated star-shape bis-carbazol-triphenylamine end-caped dendrimers was designed, synthetized and characterized as novel organic optoelectronic materials. These compounds hold triphenylamine and carbazole electroactive moieties as dendrimer core and/or periphery groups. Homogeneous and stable electrogenerated polymeric films were obtained from dendrimers over Pt and ITO electrodes. These films showed charge conductivities, reversible electrochemical behavior and electrochromic effect. The hole mobility of the electrodeposited films was found to be dependent of the dendrimeric structure and film morphologies, indicating that the shape and size of the studied dendrimers have a strong effect on their charge transport properties. These results provide data that will contribute to the systematic study for the design of new dendrimers as starting materials for conductive polymers films with potential applications in optoelectronic devices.
