Patent

CA 2700713

The present invention relates to compounds of the formula (I) wherein the substituents are as defined in claim 1, and their use as organic semiconductor in organic devices, like diodes, organic field effect transistors and/or a solar cells. The compounds of the formula I have excellent solubility in organic solvents. High efficiency of energy conversion, excellent field-effect mobility, good on/off current ratios and/or excellent stability can be observed, when said compounds arc used in semiconductor devices or organic photovoltaic (PV) devices (solar cells).

La présente invention concerne des composés représentés par la formule (I), les substituants étant tels que définis dans la revendication 1, et leur utilisation comme semi-conducteur organique dans des dispositifs organiques tels que des diodes, des transistors à effet de champ organiques et/ou des cellules solaires. Les composés représentés par la formule I ont une excellente solubilité dans des solvants organiques. Un haut rendement de conversion énergétique, une excellente mobilité à effet de champ, de bons rapports de courant de marche/arrêt et/ou une excellente stabilité peuvent être observés, lorsque lesdits composés sont utilisés dans des dispositifs à semi-conducteur ou des dispositifs photovoltaïques (PV) organiques (cellules solaires).
