Partnering opportunity

Organic derivatives for the manufacture of electronic devices

Summary

A Spanish research institution has developed organic derivatives, low cost, with possibility of modifying its molecular structure, including different substitutions, improving the properties of electronic semiconductor. These molecules present not only interesting electronic properties which make them active for the manufacture of solar cells, specifically organic photovoltaic cells, but also an intense blue color witch allows it so be used as a dye in the textile industry.

Partner sought

Industrial partners from the energy, electronic and textile are being sought to collaborate through a patent licence agreement. The partner role will be: (i) produce the product and, (ii) commercialize the product.

Description

Organic semiconductor materials The demand for energy is increasing solar energy is the future. Organic photovoltaic cells (obtain electricity from solar radiation) are the alternative to replace convencional inorganic materials, such us, silicon. Organic derivatives provide flexible mechanic, low cost and molecular design. They offer the possibility to modulate the properties (luminescence, absorption and transport of charge) as a semiconductor by adding substitutions in the chemical syntheis. They are organic derivatives of 7,7'-diazaindigo (Figure 1), where an alquilica chain have been incorporated in the nitrogen position witch make them soluble in polar organic solvents. On the other hand, the 7,7'-diazaindigo molecule is not only import from an electronic point of view but is also novel because of its intense blue color (Figure 2) witch can be modulated based on the substitution of the different substitutions in the nitrogen position. Industrial partners from the energy, electronic and textile are being sought to collaborate through a patent licence agreement.

Advantages and innovations

Then main advantages are: 1. The synthesis of the derivatives is simple and the starting materials are cheap, so the manufacturing cost would be low for their manufacture on an industrial scale. 2. The molecule is not only a very stable acceptor within organic semicondutors to be used in the manufacture of organic photovoltaic cells, but can also be incorporated into flexible and moldable area. 3. Regarding their optical properties, the compounds present a strong absorption in the UV-visible region with hight extinction coefficients. 4. On the other hand, die to its intense blue color it could be used as a dye in the textile industry.

How it works

  • Tell us about yourself
  • We’ll discuss with you
  • We put the right partners in touch

EEN help you find the right partner, rather than you going it alone.

Our role is to review and collate the most suitable submissions, and then send them to the client who posted the opportunity. We consult with you, and the client, to make the process professional and easy.

These are live opportunities. Your registration of interest on the site is just like a professional approach to a business at a networking event. To stand the best chance of success, make your submission really sing. Sell why the client who posted the opportunity should work with you. Excite them. Ask questions. Try and avoid copy and pasting words from elsewhere.

Once the client has chosen their partner, we'll introduce them over email and keep in touch with both parties to see how it's going. Sometimes things progress quickly. Sometimes because of changing priorities for either party, things progress slowly, but you never know - your next big business break could start right here.
