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.
