Synthesis and electronic properties of poly(2-phenylthieno[3,4-b]thiophene): A new low band gap polymer
- Univ. of Texas, Richardson, TX (United States). Dept. of Chemistry
A major research thrust in the field of conducting polymers is the design and synthesis of low band gap (E{sub gap}) materials. Recent work in the laboratories has focused on the structure/property relationship of poly(3-phenylthiophene)s. The extended conjugation of the phenyl group lowers the oxidation potential of the monomers compared to that of thiophene, and the redox properties of the resulting polymers can be varied by introducing substituents onto the phenyl ring. The authors were interested in developing a synthetic methodology that combined the strategies of poly(3-phenylthiophene)s with poly(2-decylthieno[3,4-b]thiophene) (PDTT) to ultimately yield a series of substituted poly(2-phenylthieno[3,4-b]thiophene)s. The synthesis and electronic properties of the parent poly(2-phenylthieno-[3,4-b]thiophene) (PTT) are reported in this paper.
