Paper Abstract

A novel family of 9,9'-spirobifluorene functionalized head-tail regular n-hexyl-substituted oligothiophenes, which exhibit good solubility in common organic solvents, has been successfully developed in this contribution. The study of the redox behavior of the spiro-type molecules indicates that their HOMO and LUMO energy levels are adjusted to match the electrode work function by varying the attaching oligothiophene moieties and their attaching patterns to 9,9'- spirobifluorene. The two series of spiro-type oligothiophenes still remained the similar electrochemical properties of common oligothiophenes while their processability and morphologic stability being improved by the spiro-junction.
