Abstract

We successfully synthesized a new organodisulfide poly 1,2-bis(thiophen-3-ylmethyl)disulfane by a facile preparation method. The types of the chemical groups of poly-3-thienylthiophene were characterized by Fourier transform infrared spectroscopy (FTIR). The electrochemical properties of S–S bonds redox behavior in the organodisulfides were investigated in CH3CN/0.1M [Bu4N] [PF6] solution. The separation of the anodic and cathodic peak potentials for poly 1,2-bis(thiophen-3-ylmethyl)disulfane is 180mV. The results indicated that poly 1,2-bis(thiophen-3-ylmethyl)disulfane has an excellent electrochemical reversibility. The average specific capacity of 230mAhg−1 for poly-3-thienylthiophene is about 2 times higher than that of LiCoO2.
