ORMECON® D Series
Organic Metal Dispersions for Polymer Electronics

Organic Metals: Background

Organic Metals are insoluble and unmoldable. As such, the only way to process it is by dispersion technique.

In the late 1970s Dr. Bernhard Wessling of Ormecon International (acquired in 2008 by Enthone Inc.), undertook basic research and developed dispersion technology based products and processes for the application of Organic Metals. Based on these, Ormecon developed a wide range of pure dispersions which do not contain any film forming resin systems or other insulating polymer matrices.

ORMECON® D Series

ORMECON® D Series Organic Metal Dispersions primarily consist of the Organic Nanometal® in colloidal form (between 10 and around 100 nm particle size, dependant on the dispersion medium) and the dispersion medium, being either water or organic solvents.

ORMECON D dispersions are available in water, xylene, toluene, isopropyl alcohol, and ethanol media. The dispersions are used in basic and applied research for polymer electronics. The dispersions cover a wide range of conductivity between 102 and 10-7 S/cm. The dispersions usually are applied by spin coating. Based on the media, the conductivity range for the dispersions can be tuned between 10-6 S/cm up to 102 S/cm.

The main application area for these materials is ITO replacement. Initial testing results have demonstrated that ORMECON D Series Dispersions have provided better results compared to ITO (front electrode for electroluminescence).

The Institute of Applied Photophysics, Technical University Dresden, Dr. Fehse / Prof Karl Leo investigated ORMECON D 1033 W as a replacement of ITO in OLEDs. Read more.
