In this work we have designed and synthesized a new series of benzyl ether type terthiophene terminated dendrimers. These dendrimers were designed to act as precursor polymer, which bears the electroactive terthiophene group that can be crosslinked either by chemical or by electrochemical methods to form a conjugated polymer network. The benzyl ether groups posses a lower Tg backbone, which can allow more reorientation of the peripheral terthiophene groups, resulting in properties that are believed to be different from the class of linear polymers such as polythiophenes. The synthesized dendrimers were very soluble in common organic solvents such as methylene chloride, chloroform, and THF. These dendrimers were characterized by NMR, gel permeation chromatography, MALDI time-of-flight, UV-vis, fluorescence, and thermo gravimetric analysis.
