PEDOT-TMA

From Wikipedia, the free encyclopedia

Poly(3,4-ethylenedioxythiophene)-tetramethacrylate or PEDOT-TMA is a p-type conducting polymer based on 3,4-ethylenedioxylthiophene or the EDOT monomer. It is a modification of the PEDOT structure. Advantages of this polymer relative to PEDOT (or PEDOT:PSS) are that it is dispersible in organic solvents, and it is non-corrosive. PEDOT-TMA was developed under a contract with the National Science Foundation, and it was first announced publicly on April 12, 2004 ^[1]. The trade name for PEDOT-TMA is Oligotron. Oligotron was featured in an article entitled "Next Stretch for Plastic Electronics" that appeared in Scientific American in 2004 ^[2]. It was also featured in an article entitled "Light, and magic" in the Materials Science section of The Economist ^[3].

The U.S. Patent office issued a patent protecting PEDOT-TMA on April 22, 2008 ^[4].

[edit] Applications

In a recent study ^[5] by researchers at General Electric, PEDOT-TMA was used in the hole injection layer in a series of OLED devices. They have also filed a patent application to protect this invention ^[6].

PEDOT-TMA has also been used as a key ingredient in ion selective membranes ^[7].
